How animal enclosures are designed to meet the needs of laboratory animals

Having worked in animal research for over 14 years now I have not only gained a comprehensive knowledge of the requirements for animals used in research but have also seen significant improvements in this field. Currently, I work at King’s College London as a Site Manager where I oversee three animal units.

The role of an animal technologist varies dependent on experience but all are there to provide the best possible life to animals in research. Trainee animal technologists will often perform general husbandry duties such as cleaning cages, feeding, and watering, whereas senior technologists may be involved in colony management, scientific procedures etc.

During my career, and the many tours of research labs I’ve given, one of the common discussion is the type of cages used and how they vary so much between species.

Requirements for housing research animals in the UK are stipulated by Home Office and Animals (Scientific Procedures) Act, 1986 as well as any additional institutional requirements beyond this law. Providing the correct type of environment is essential for species to exhibit their natural behaviour.

Example of UK minimum cage sizing for M. mulatta

Housing requirements vary between species but here are some examples of why cages are designed in such a way:

Primates

Primate caging is typically tall as this enables the animals to feel more secure, as in the wild they would use the trees to climb high and get away from prey. Providing higher cages also allows for a more complex environment. Bars are often horizontal to allow the animal to climb the cage and maximise this as much as possible. Cages are normally made out of steel to ensure the animals are safely contained and also withstand potential damage in what are often a strong and intelligent species.

Cages are often multi-tiered to allow primates better utilisation of cage height and enable primates to get away from each other when necessary.  Environmental enrichment such as mirrors and perches provide further security to primates.

Primates are socially housed in multi-tier caging. The perches allow the primates to watch what is going on around the room.

Rodents

Rodents have much smaller cages which are normally made up of a plastic, such as polysulfone. These plastics can withstand high temperatures during cleaning and have been shown to last a long time. Traditionally, animals were kept in open top caging but in recent years there has been a movement towards individually ventilated cages (IVCs). IVCs provide a more stable environment by having sealed caging and using air handling units for filtration; this has, in turn, provided a better environment for animal welfare and research. Controlling for the environment can both help control experimental variables, and prevent risks to animal health from external pathogens.

While the caging appears to be relatively small for rodents it is designed around the need of the animals. Rodents are often social species and in some cases larger spaces can cause anxiety due predator/prey relationships.

Environmental enrichment is used to encourage natural nesting behaviours which can be seen in the wild. In recent years red boxes have been implemented in some cages, humans can see through these but animals don’t see through this colour in the same way, therefore this allows better monitoring while making animals feel safe and secure.

Individually Ventilated Cages

Rabbits

Rabbits are often housed in floor pens as this provides space to exercise and express their social behaviour. Rabbits which are kept grouped housed tend to show less stereotypic behaviour and greater activity. Previously, rabbits were predominantly housed in single cages which caused more stress to the animals.  Enclosures are normally made up of wood frame with metal bars or completely metal frame with very small holes to prevent animals escaping.

Environmental enrichment such as cardboard boxes, hay/straw and raised areas can also provide more security and natural behaviours therefore reducing any abnormal behaviour which may be seen otherwise.  As albino rabbits are often used in research, boxes also provide a darker place to prevent damage to the retina of the eye.

Final thoughts

As humans we often believe that larger housing is better, just look at people who often want a huge home, but this doesn’t mean that an animal will be comfortable with this. The key is to tailor this to each species/individual’s needs for the highest welfare standards. Animals which naturally live in holes, or nests, often feel comfortable with less space compared with other animals. Other additions to accommodation such as environmental enrichment can enable expression of natural behaviour further and have significantly increased in recent years, no more barren cages!

In my 14+ years working with research animals, I have seen a huge amount of change. Improvements in caging and enrichment benefit not only the animals, but the pursuit of good science as well, and we should welcome it. I am also a strong believer that this has also improved the morale of staff, after all we all want the best for animal welfare which in turn will lead to good science.

Animal Research in South Korea in 2016

In February 2017 the Animal and Plant Quarantine Agency (APQA) of South Korea released its animal research numbers for 2016. We spoke to the Animal Protection & Welfare Division and have been able to get a translated copy of these figures. The tables below were produced by the APQA, and we thank Dr Lee for providing these figures.

In 2016, South Korea used 2,878,907 animals in research, up 14.8% from the previous year.

Animal research in South Korea for 2016 by species

Rodents, fish and birds accounted for over 97% of animals used in research – similar to figures found in Europe. Most of the rise in animal experiments came from an increase in rodents (+19.5%), though numbers for fish (+15.2%) and birds (+60.7%) also contributed. There were falls in several categories, including primate experiments, which fell 18.8%.

Severity of animal experiments in South Korea

South Korea also produced severity statistics, similar to those in Europe. 2.6% of research showed no harm to the animal, 28.4% was mild, 35.5% was moderate and was 33.4% severe.We are unclear if these categorizations are based on pre-experiment licenses (what the researcher believed the severity would be) or post-experiment evaluation (what the researcher saw the severity to be).

Trends in South Korean animal experiments 2008-2016

The number of animals used in research has risen sharply over the last nine years, up 279% over the period, rising at a fairly steady rate of over 250,000 animals per year. To see why, take a look at a graph, produced by Nature, on the growth of R&D in South Korea over the same period.

The huge rise in spending on basic and applied research means that animal experiments were likely to rise (and did) over the same period. In 2013, South Korea had more researchers per thousand people in employment (12.84) than Japan (10.19), the USA  (8.81) or Germany (8.54). Medical and health sciences were the largest discipline (by publications) in South Korea (see Nature article).

Open letter: Private workshop on the “necessity” of monkey research does not represent broad public interests or the scientific community

This weekend there will be science marches around the globe. Scientists and science proponents will gather to provide a visible sign of support for work that benefits the public, the environment, and the world in innumerable ways. The march has been highly publicized  – rightfully so, because it serves as a reminder that scientific research and scientists can be threatened in a variety of ways that can have consequences with breadth and depth that should be of concern for society as a whole.

This week there will also be another event that has potential for consequences for science and public health. But it is neither a public event, nor one that has been publicized.

The private event is a workshop titled, “The necessity of the use of non-human primate models in research.” The workshop is supported by Johns Hopkins University and is organized by Prof. Jeff Kahn in the Berman Institute for Bioethics, with participants that include philosophers, bioethicists, a leader of the Humane Society of the US, veterinarians, and scientists– all by invitation only (see roster in workshop agenda below). Its stated goals and approach are: “To help address the issues of the use of NHPs in research, we are convening this working group to examine the science, ethics, and policy aspects of the use of NHPs in biomedical and behavioral research and testing, with the goal of identifying consensus findings, conclusions, and recommendations. The focus of the working group will be to evaluate the current and potential future uses of NHP models, drawing on the approach used in the 2011 IOM Report “Chimpanzees in Biomedical and Behavioral Research: Assessing the Necessity” (IOM, 2011).

The group lists as their objective: “The product(s) of the working group process will be a report or series of reports based on the working group’s expert analysis, which will include principles and criteria for assessing the necessity of the use of NHPs in research.” (emphasis added)

Detail is here: Animal Working Group Meeting 1 Briefing Book

In other words, the working group, privately convened, is intent on replicating the 2011 IOM process applied to chimpanzees in order to produce their own principles and criteria for assessing nonhuman primate research broadly. This process should cause grave concern for scientists and for the public who rely on research conducted with nonhuman primates.

The scientific community has publicly weighed in on the necessity of primate research. Most recently, the National Institutes of Health convened a working group to consider nonhuman primate research and concluded “that the oversight framework for the use of non-human primates in research is robust and has provided sufficient protections to date.” Similarly, a letter from over 400 scientists, including Nobel Laureates, rejected a claim from notable public figures that neuroscience research with non-human primates is no longer useful. The hundreds of scientists argued that, “primate research was still critical for developing treatments for dementia and other debilitating illnesses.” (https://www.theguardian.com/science/2016/sep/13/brain-experiments-on-primates-are-crucial-say-eminent-scientists)

Consideration of the ethical justification for research and of the care for animals in research occurs at many levels and in public space. Public health, including the interests of patients and of society as a whole, is integral to those decisions. The scientific community provides expert knowledge about what types of studies are needed for progress in the basic understanding of biology, brain, behavior, and disease and also about how to move forward with new prevention, intervention, and treatment to address health challenges. Funding agencies, such as the National Institutes of Health, are charged by the public to make decisions about science and do so through a process that involves multiple layers of expert review. Federal agencies also oversee research and standards of care for humans and animals involved in studies and provide opportunities for the public to comment on standards and to benefit from decisions.

The private workshop has the appearance of being secretive while also directly opposing the processes in place for responsible public decision-making. As such, it appears to be yet another attempt to influence decisions about science without adequately representing either public interests or the breadth and depth of expertise in the scientific community. Without adequate scientific representation the workshop conclusions cannot be taken as adequately representative of the current state of scientific knowledge. Without adequate representation of the public agencies that safeguard societal interests in scientific and medical progress the workshop conclusions cannot be taken as representative of fact-informed, balanced consideration of research.

Finally, without consideration informed by understanding the fundamental characteristics of the scientific process, the workshop conclusions will only reflect an agenda biased to reach a particular conclusion. As it is framed, it appears that the question of “necessity” is one that cannot account well for the role of basic research, of uncertainty, and of the difference between decisions based in a particular set of values and decisions about the best scientific course of action to answer questions and advance understanding of human and animal health.

For all of these reasons, the reports emanating from this private workshop must be critically examined with healthy skepticism, rather than taken as an authoritative account. We remain concerned that the products of a workshop will serve to advance an agenda that is harmful to public interests in scientific research.

Research Roundup: A new approach to treating Parkinson’s, designer pig organs, the benefits of dragon blood, and more!

Welcome to this week’s Research Roundup. These Friday posts aim to inform our readers about the many stories that relate to animal research each week. Do you have an animal research story we should include in next week’s Research Roundup? You can send it to us via our Facebook page or through the contact form on the website.

  • Scientists may have discovered a new way to treat Parkinson’s disease (PD), a devastating neurological disease that causes tremors, rigid muscles, and changes in speech. In PD, a person’s brain cells (neurons) die causing a reduction in the neurotransmitter, dopamine. Researchers in Sweden were able to reprogram human astrocytes – brain cells that normally support the functions of neurons – to behave more like dopamine producing neurons. They did this by bathing the astrocytes in a petri dish in a number of molecules that affect changes in the cell’s DNA. This proof of concept allowed researchers to take the next step and try this therapy in a mouse model of PD. Injecting the same cocktail of molecules into the brains of PD mice caused the astrocytes to become more like the dopamine producing neurons, and this change lessened the PD symptoms in the mice. Obviously, many more studies are needed before this potential therapy can be tried in human patients with PD, but this is an exciting advancement in our quest to treat this disease. This research was published in Nature Biotechnology.

Mice were key to this Parkinson’s breakthrough

  • A new study finds that a reovirus may be implicated in the development of celiac disease. Celiac disease is a serious autoimmune disease where the ingestion of gluten, leads to damage of the small intestine. Gluten is found in many common foods, and is the general name for wheat derived proteins. “It affects 1 in 100 people worldwide, and 2.5 million Americans are undiagnosed and are at risk for long-term health complications”. Mice, were infected orally with two derived forms of a human reovirus, T1L and T3D; both capable of infecting the hosts` intestine but affecting its functioning in different ways. They found that while mice were able to successfully clear the virus from the system; exposure to the virus can disrupt intestinal homeostasis, lead to a loss of oral tolerance to the antigens produced by the body, and promote immunopathology similar to the symptoms of celiac disease. This study will of course need to replicated and further research investigating other reoviruses and the subsequent link to the development of celiac diseases firmly established. This study, using mice, does however, provide hope for the millions of individuals suffering from celiac disease and if a strong link to reoviruses is established; can lead to the development of a vaccination. The research was published in Science.
  • A promising vaccination for Zika virus has been found, reducing the occurrence of congenital abnormalities in mice. Zika virus is an emergent global health threat, that is transmitted by mosquito bites and more recently it has been discovered that it can be passed on via sex with an infected person. The most debilitating effects of the virus are death in the young and elderly are with compromised immune systems and perhaps most strikingly birth defects — in particular, microcephaly; a sign of incomplete brain development. For the first time, these researchers tested a live attenuated version of the Zika virus in mice. In comparison to an inactivated vaccine, live attenuated vaccinations have the advantage of single-dose immunization, rapid and robust immune response, and potentially long-lived protection. They found that this live attenuated vaccination was able to confer sterilizing immunity (complete protection from infection), a robust T-cell immune response, and a promising safety profile; similar to that of other clinically approved vaccinations. This study was published in Nature Medicine.

  • A new study finds that the human body’s peripheral nervous system could be capable of interpreting its environment and modulating pain. The sensation and perception of pain has historically been associated with the brain and the spinal cord (central nervous system(CNS)) and drugs for pain target the CNS. However, these drugs sometimes lead to unintended side effects such as addiction and tolerance. Drugs which target the peripheral system may allows us to avoid these unintended side effects. Using mice, these researchers demonstrated that the peripheral nervous system was able to interpret the type of stimulation it was sensing, although further research is needed to figure out how these sensations are interpreted by the brain. While further replication and validation is needed, this study widens our view of pain, its sensation and potential means of treatment. This study was published in the Journal of Clinical Investigation.

  • Luhan Yang, Chief Scientific Officer at eGenesis, is working to create ‘designer pigs’ which could be used to help alleviate the organ crisis. By inserting up to 12 human genes into pig ova they hope to overcome the rejection problems which currently prevent xenotransplantation from providing viable organs for human use. Yang hopes the use of the gene-editing technique CRISPR will make it possible to create human-animal hybrid organs that can be used to save lives.

  • New study finds that variant of protein in komodo dragon blood (VK25) contains antimicrobials that may one day form the basis of a new antibiotic. Researchers at George Mason University synthesized a new molecule,DRGN-1, based on a peptide found in the blood of the Indonesian lizard. This molecule was shown to promote healing in mice with wounds infected with Pseudomonas aeruginosa and Staphylococcus aureus. This synthetic compound also made these bacteria cell membrane more permeable – making it easier to kill these bacteria. The research was published in Biofilms and Microbiomes

Disappointing lack of context by Cruelty Free International, as worst press release on animal testing numbers is revealed

Cruelty Free International (CFI), a British-based animal rights group (formerly known as the British Union for the Abolition of Vivisection), has produced its annual press release about animal research numbers at British Universities. The release, entitled: “Disappointing lack of progress at UK universities as worst offenders for animal testing are revealed”, is full of hyperbole, half-truths and even a few outright factual mistakes. The release is likely to leave those readers who have little prior knowledge of animal research, with a less accurate impression of what it entails than if they’d consulted the universities themselves. The full CFI release can be found at the bottom of this article.

The press release begins with

Cruelty Free International has today revealed the five worst offending universities for animal testing in the UK, which are each responsible for carrying out experiments on over 175,000 animals per year. The universities of Oxford, Edinburgh, Cambridge, University College and King’s College London, forced 997,839 animals to suffer in experiments in 2015. This represents a collective increase of 7% compared to 2014.

This might be more “revealing” if it wasn’t for the fact that these universities (and five more) came together six months earlier to proactively press release their 2015 animal research numbers. This release included nine case studies of research being done at the institutions in order to provide additional context to the numbers. The article was picked up by the Huffington Post (and a few other outlets).

From Huffington Post UK

The article included the number of procedures on animals carried out by each institution:

Perhaps CFI didn’t see it, you may ask? Well no, CFI’s Katy Taylor is quoted in the Huffington Post article, responding to the information provided by the Universities.  Interestingly, CFI ends the first paragraph of its press release by noting that this represents a 7% rise by the top five universities over their 2014 statistics. This rise is exactly in line with the 7% rise in animal experiments that happened across all institutions in the UK (on average).

Cruelty Free International goes on to provide a table of the numbers (which they erroneously describe as “number of animals” when they mean “number of procedures” – a rookie mistake for an organisation which claims to be an authority on the issue). It notes the rise in the number of procedures at four out of the five universities, but describes the (very small) decline in numbers at the University of Oxford as “virtually no change”. That probably sounded better for their release. CFI also gets the number of procedures at the University of Cambridge wrong – it is 181,080, a number which is freely available on the university website.

The five universities mentioned also appear together in another list – they account for five of the top six British Universities on the QS World University ranking. Perhaps what CFI describe as the “worst universities for animal experiments” are in fact some of the best universities in the world for biomedical research (all five are also in the top 50 world institutions for “biological sciences”) and for advancing human health.

These are the six top ranked British Universities on the world university leagues tables. The numbers on the left represent their position in the world, including institution outside the UK.

CFI’s press release then goes on to make unverified claims about things going on at the five universities. Because CFI provides no evidence or paper references for the claims that, for example, monkeys were “deprived of food or water”, or were “restrained for hours”, it is impossible to speak to the veracity of these claims. However, similar claims by other animal rights groups have often been found to be either false or misleading.

Dr Katy Taylor, CFI’s Director of Science, who is quoted in the press release, suggests these universities should be leading in “replacing and reducing animal testing”. Setting aside the fact that these institutions do animal research, and very little animal testing (which is a term for safety tests, usually done by pharmaceutical companies and CROs, and require by law before potential new medicines can move into human trials), the truth is that these institutions are leading the way in both animal and non-animal methods. For instance, researchers at the University of Cambridge have won NC3Rs Prizes, for the Replacement, Refinement and Reduction of animals in research, in 2008, 2009, 2011 and 2013; Oliver Britton at the University of Oxford won the prize in 2014 for a computer model of cardiac electrophysiology; and Dr Anna Williams at the University of Edinburgh was highly commended in 2011 for her work on cell cultures which can reduce the number of mice needed to test MS treatments. King’s College London, meanwhile, has developed a number of animal alternatives, such as this artificial gill system which reduces the need to use fish, and University College London is the home of the Replacement of Animals in Research Conference  alternatives conference. Just because an institution is doing great work Replacing and Reducing animal research, doesn’t mean overall numbers will come down – as this is influenced by many factors.

Finally we come to one of trickier claims. Katy Taylor goes on to say:

63% of the 65 universities that reported testing on animals in 2015 still do not publish their animal testing statistics online, despite claiming that they agree there should be more transparency.

It is worth noting that the Universities that do the most animal research DO publish their statistics online. A quick search found 22 institutions that definitely published their statistics – they accounted for 1,612,166 procedures, of the 1,977,928 procedures conducted by all universities and medical schools in 2015 (Table 11). So rather than saying 63% of universities do not publish their figures (remembering that some of these institutions may only do a few dozen procedures), it might be more meaningful to say that 81.5% of procedures are accounted for in the data published by universities. It is unclear where CFI’s figure of 1,920,171 animals comes from as it does not appear in the 2015 statistical report.

Taylor then goes on to attack the University of Bristol over its statistics:

Bristol University now stands alone as the only university experimenting on animals that still refuses to provide its figures on the grounds that it does not hold the information centrally, despite promising to update its record keeping.

The Freedom of Information Act sets limits on the time that institutions can be expected to spend answering any single FOI question. The Information Commissioner’s Office has agreed with the University of Bristol and has upheld their claim that the University would be unable to provide the information asked of it due to the excessive lengths of time it would take to collate. The institution is in the process of changing how this information is collated and has expressed its intention to proactively publish this in the future.

It is an open question as to why, six months after a press release from UK universities went the extra mile to inform the general public about how many animals were used for what purposes at these institutions, anyone would strip it of its context and case studies, add the word “revealed” and republish it alongside their own anti-animal research diatribe.

Given that Cruelty Free International regularly calls for greater transparency in animal research, surely they should be welcoming the work that top universities are doing to provide more information about the research they conduct – rather than using this information as the basis of a press release criticising such research. We must hope that journalists choose to report the accurate numbers and representative case studies of medical progress released by the universities, rather than the account of an organisation whose sole purpose is to end the use of animals in experiments.

Press Release sent by Cruelty Free International
Disappointing lack of progress at UK universities as worst offenders for animal testing are revealed
Nearly 1 million animals tested at five worst universities for animal experiments
Cruelty Free International has today revealed the five worst offending universities for animal testing in the UK, which are each responsible for carrying out experiments on over 175,000 animals per year. The universities of Oxford, Edinburgh, Cambridge, University College and King’s College London, forced 997,839 animals to suffer in experiments in 2015 (the year for which the most recent figures are available). This represents a collective increase of 7% compared to 2014.
In 2015 the following numbers of animals were used by each of the top five universities:
  • Oxford University (226,214) – virtually no change on the previous year
  • Edinburgh University (212,695) – 6% increase
  • University College London (202,554) – 15% increase
  • Cambridge University (181,090) – 13% increase
  • King’s College London (175,296) – 6% increase
According to the Home Office, testing in universities continues to make up almost 50% of all animal experiments in Great Britain. Despite claims that animals are only used in tests where there is no viable alternative, the figures collected for 2015 by Cruelty Free International under Freedom of Information (FOI) requests or accessed from university websites show a collective increase of 7.5% in animal testing at universities from the previous year. In 2015, over 1,920,171 animals were used in tests.
Four of the worst five universities reported subjecting macaque and/or marmoset monkeys to experiments (all except for Edinburgh). Recently published experiments from these institutions included monkeys being deprived of food or water, being restrained for hours in ‘primate chairs’ to perform repetitive computer tasks, having electrodes surgically implanted into their skulls, coils implanted in their eyes, having portions of their brain damaged, being trapped inside plastic boxes or injected with antidepressant drugs.
Experiments by university staff were also carried out on rabbits, sheep, guinea pigs, ferrets, fish, birds, frogs, rats and mice. Recent examples include blocking or cutting the arteries of pigs and rabbits to induce heart attacks, and purposefully stressing rats by restraining them inside plastic tubes, restricting their food and keeping them in isolated, barren cages.
Dr Katy Taylor, Director of Science at Cruelty Free International, said: “Our top universities should be leading the way in replacing and reducing animal testing, yet they remain some of the biggest users of animals in Britain. The public wants to see meaningful and lasting changes towards ending the use of animals in laboratories; our universities should be setting the example not adding to the problem.”
63% of the 65 universities that reported testing on animals in 2015 still do not publish their animal testing statistics online, despite claiming that they agree there should be more transparency. Bristol University now stands alone as the only university experimenting on animals that still refuses to provide its figures on the grounds that it does not hold the information centrally, despite promising to update its record keeping. A Cruelty Free International complaint to the Information Tribunal about this failure is ongoing [1].

Research Roundup: Death of a pioneer, 2017 Brain Prize, and unsubstantiated claims by PETA

Welcome to the first in a series of weekly Research Roundups. These aim to inform our readers about the many stories that relate to animal research each week.

Do you have an animal research story we should include in next week’s roundup? You can send it to us via our Facebook page or through the contact form on the website.

  • Thomas Starzl the father of organ transplantation has died. Beginning with his work on liver transplantation in dogs in the 1950s, and subsequent refinement of the procedure using livers from pigs and primates, today “more than half of the liver-transplant patients who underwent surgery in 1998 were alive ten years later, and in 2009, almost 50,000 Americans carried a transplanted liver” (Lasker Foundation).” Read more about this here and here.

The father of organ transplantation, Thomas Starzl.

  • 2017 Brain Prize announced – Peter Dayan, Ray Dolan and Wolfram Schultz. Collectively, their work examines the ability of humans and animals to link rewards to events and actions. This research, involving non-human primates, provides valuable insights into motivation to perform both positive and negative behaviour, how those behaviours regulate emotions such as happiness and how dysregulation may affect addictive/compulsive behaviours such as gambling. Read more about this here.

  • An unannounced four-day inspection of the animal research facilities at the University of Pittsburgh found no wrongdoing. The inspection was triggered by unspecified allegations by the animal rights group PETA, though USDA officials could not find evidence corroborating the claims by PETA. This is not the first time we have noted that animal rights groups claims against labs which cannot be substantiated by inspectors. More here.
  • Tasmanian devil cancer is a major threat Tasmanian devils with more than 80% of the population being wiped out since it emerged 20 years ago. Fighting cancer with cancer, and in a culmination of 6 years of research, scientists have managed to achieve a 60% survival rate (3 out of 5). The application of animal research takes all forms, and this is a good example of techniques being developed in the lab on nonhuman animals being used to save other nonhuman animals. More here and here.

Nonhuman primate research gives us otherwise impossible treatments

stuart-bakerLast week, Dr. Stuart Baker, a Professor of Movement Neuroscience at Newcastle University, wrote an article in The Conversation detailing not only the lifesaving research that nonhuman primates contribute to, but also the exceptional care they receive while contributing to human health. Stuart last week also published a paper describing his laboratory’s development of a new device that helps stroke patients to recover, a device that was dependent on development first in rhesus monkeys.  In his piece in The Conversation, Baker highlights the following:

  • Why it is important to understand how the brain controls movement
  • Why nonhuman primates are superior to other animal models for this type of research
  • The state-of-the-art care his laboratory primates receive

Why it is important to understand how the brain controls movement

“We typically take the ability to move in a fluid, coordinated way for granted,” Baker writes. Yet many adults “suffer damage to the brain’s pathways for movement, for example after a stroke. Suddenly, everyday tasks become a tiring, frustrating struggle.” Baker studies how the brain controls movement in order to understand the connections between our brains and our limbs. By understanding how brain cells adapt their neuronal activity during movements, how neurons are connected, and how they reconfigure after injury, Baker can then develop devices for therapeutic treatment like the one he published about in The Journal of Neuroscience last week.

Why nonhuman primates are superior to other animal models for this type of research

In his article in The Conversation, Baker emphasized the need for nonhuman primates in movement neuroscience research. In order to understand the deepest inner workings of the brain – those that don’t contribute to scalp recordings, which can be used in humans – one must probe deeper than the surface. Baker uses an analogy of an airport: “When we record from the scalp, we average the signals from many millions of cells. It’s a bit like placing a microphone on the ceiling of an airport departure hall, and measuring the sound levels.” This type of information is useful because it can tell you “what times of the day the airport is busy.” But “some aspects of the airport’s operations – those outside on the tarmac – would be missed.” Similarly, Baker says, some brain centers that control movement are so deep beneath the skull that a deeper exploration beyond scalp recordings is required. Enter monkey models: “Many pathways for movement control are different between primates such as humans and other animals such as rats. Only a primate model can give us information which is relevant to human diseases.

The state-of-the-art care his laboratory primates receive

Stuart is well aware that there are inaccurate and baseless claims that his lab animals suffer. In The Conversation, he describes in detail the care his monkey receive, from positive reinforcement training so that they learn to perform complex tasks with their hands or arm to undergoing surgery “in a fully equipped operating theatre, with sophisticated anaesthetics and painkilling medication borrowed from state-of-the-art human care.” The monkeys are carefully monitored to ensure they are not distressed or in pain.

Baker also emphasizes the “huge effort [that] goes into minimizing suffering every day.” This effort is not optional, but “an integral part of what we do and who we are.”

Baker’s article is a wonderful example of the type of transparency that scientists should engage in more frequently. Without such candor, the public is unaware of the extent to which animal models contribute to lifesaving therapeutics – and also of the excellent care they receive from the people who truly love working with them.
