Podcasts about marmosets

In this mind-bending installment, hosts Jaysin and John strap on their astro-chaps to blast off toward the newly discovered Marmoset Moon Base—a hidden lunar colony run by multilingual primates with a flair for interpretive jazz tap. Upon arrival, they discover the Marmosets are embroiled in a heated turf war with a clandestine order of mozzarella monks, all vying for a revered cosmic artifact: The Nacho Oracle, said to bestow infinite knowledge on anyone who can read the cheese crystals without dissolving into a fountain of jalapeño tears. While Jaysin attempts to prove his worthiness by reciting haiku in the Marmoset Queen's personal yodeling chamber, John embarks on a daredevil cheese-scrying quest in the subterranean catacombs, where bell-bottomed salamanders whisper cryptic marketing tips for interstellar caravans. Together, they'll face off against robotic rodents that fuel their pogo sticks with liquid guacamole, forging alliances and uncovering the spicy secrets that unite the cosmic dairy realms. Will Jaysin's poetic yodeling skills impress the Marmosets enough to gain access to the Nacho Oracle's gooey wisdom? Can John survive the jalapeño tears that threaten to turn him into a human quesadilla? Tune in for an out-of-this-world blend of lunacy, lactose, and leaps of faith as Jaysin and John attempt to bring peace (and the perfect topping ratio) to the Marmoset Moon Base.

H., Lindquist, K., Tram, M., Perez, D., Mecklenburg, J., Salmon, A., Merlo, J., Corey, T. Abstract: Myogenous temporomandibular disorders (TMD-M) are the most prevalent group of painful orofacial conditions, and the second most frequent among musculoskeletal pain conditions. TMD-M is associated with an increased responsiveness of nerves innervating the masseter (MM), temporal (TM), medial pterygoid closing (MPM) and lateral pterygoid gliding muscles (LPM). Treatment of this disorder remains difficult and is further complicated by each muscle having diverse and functionally distinct nerve innervation. This study examined expression of sensory markers in MM, TM and LPM of adult male common marmosets, a type of non-human primate. Using immunohistochemistry, we found that masticatory muscles were predominantly innervated with A-fibers (NFH+). All C-fibers (pgp9.5+/NFH-) observed in masticatory muscles were peptidergic (CGRP+) and lacked antibody labeling for mrgprD, trpV1 and the silent nociceptive marker, CHRNA3. The proportion of C- to A-fibers was highest in LPM, while MM had a minimal percentage (6-8%) of C-fibers. Interestingly, C-fibers in masticatory muscle may have myelin sheath, since many NFH- nerves were labeled with GFAP+. A-fiber types were also dissimilar among these muscles. Thus, there are substantially more peptidergic A-fibers (CGRP+/NFH+) in TM and LPM compared to MM. Almost all A-fibers in MM expressed trkC, with some of them having trkB and parvalbumin (PV). In contrast, a lesser number of TM and LPM nerves expressed trkC, lacked trkB and had fewer PV+ fibers in LPM. Along with sensory fibers, the masticatory muscles contain sympathetic fibers (tyrosine hydroxylase; TH+), which are located around blood vessels. This TH expression was absent in trigeminal neurons. Overall, the masticatory muscles of male marmosets have distinct expression patterns when compared to each muscle of the jaw and cutaneous fibers innervated by DRG neurons.

Abstract: Astrocytes perform multiple essential functions in the brain showing morphological changes. Hypertrophic astrocytes are commonly observed in cognitively healthy aged animals, implying a functional defense mechanism without losing neuronal support. In neurodegenerative diseases, astrocytes show morphological alterations, such as decreased process length and reduced number of branch points, known as astroglial atrophy, with detrimental effects on neuronal cells. The common marmoset (Callithrix jacchus) is a non-human primate that, with age, develops several features that resemble neurodegeneration. In this study, we characterize the morphological alterations in astrocytes of adolescent (mean 1.75 y), adult (mean 5.33 y), old (mean 11.25 y), and aged (mean 16.83 y) male marmosets. We observed a significantly reduced arborization in astrocytes of aged marmosets compared to younger animals in the hippocampus and entorhinal cortex. These astrocytes also show oxidative damage to RNA and increased nuclear pTau (AT100). Astrocytes lacking S100A10 protein show a more severe atrophy and DNA fragmentation. Our results demonstrate the presence of atrophic astrocytes in the brains of aged marmosets. Copy rights belong to original authors. Visit the link for more info Podcast created by Paper Player, LLC

P., Sedaghat-Nejad, E., Pi, J., Shadmehr, R. Abstract: We prefer to decline effortful rewards, but if the circumstances require it, we will move only slowly to harvest them. Why should economic variables such as reward and effort affect movement vigor? In theory, our decisions and movements both contribute to a measure of fitness in which the objective is to maximize rewards minus efforts, divided by time. To test this idea, we engaged marmosets in a foraging task in which on each trial they decided whether to work by making saccades to visual targets, thus accumulating food, or to harvest by licking. We varied the effort cost of harvest by moving the food tube with respect to the mouth. Theory predicted that the subjects would respond to the increased effort costs by working longer, stockpiling food before commencing harvest, but reduce their movement vigor to conserve energy. Indeed, in response to the increased effort costs of harvest, marmosets increased their work duration but reduced their movement vigor. These changes in decisions and movements coincided with changes in pupil size. As the effort cost of harvest declined, work duration decreased, the pupils dilated, and lick and tongue vigor increased. Thus, when acquisition of reward became effortful, there was a global change in the state of the brain: the pupils constricted, the decisions exhibited delayed gratification, and the movements displayed reduced vigor.

Abstract: The brain at rest or during periods of relative inactivity, complex dynamical patterns of activity spontaneously form over the entire brain. In this study, we plan to clarify the convergence and divergence of spontaneous brain activity across humans and marmosets. We investigated the spontaneous brain dynamics of marmosets, and compared its convergence and divergence with human neuroimaging results. We identified seven representative FC patterns (FC states) in the resting-state activity of marmosets. The most prevalent two FC patterns (VC1 and VC2) corresponds to a state of BOLD coherence of primary visual and auditory processing regions. Our results suggested that the spontaneous activity does reflect the inherent properties of the brain of marmosets. Copy rights belong to original authors.

Lab Rat Chat - Episode 30 with Dr. Agnès LacreuseIn this episode of Lab Rat Chat, Jeff and Danielle chat with Dr. Agnès Lacreuse, PhD, who is a researcher at the University of Massachusetts in the Department of Psychological and Brain Sciences Department.She utilizes nonhuman primates in her research in order to better understand neurocognitive aging and pathological aging processes, such as those involved in Alzheimer's disease. Two-thirds of Alzheimer's disease cases in humans are women. 2/3 of AD cases in humans are women. For this reason, we also aim to understand how changes in sex hormones, especially estrogens, affect brain and cognitive aging in females.Topics discussed in this episode:Dr. Lacreuse's extensive and impressive background and her journey to get where he's at in her career today.What Alzheimer's disease is, who is primarily affected, how it develops, and the estimated number of people living with the disease in the United States.Why nonhuman primates, particularly Marmosets, are best suited to study Alzheimer's compared to rodents, and why alternative models (e.g., organs on a chip, computer models, etc.) are not viable options.The future application of her research on the human population and what it means for those predisposed or already suffering from the devastating effects of Alzheimer's.Purchase Lab Rat Chat merch and help support our podcast and biomedical research!https://labratchat.myteespring.co/Sign up for the Lab Rat Chat newsletter!https://www.amprogress.org/raising-voices/lab-rat-chat/Resources & Links:Animal models of Alzheimer's disease embrace diversity | Lab Animal (nature.com)Americans for Medical ProgressAmericans for Medical Progress COVID-19 ResourcesFollow us on Twitter!

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.10.10.511640v1?rss=1 Authors: Coop, S. H., Bunce, G. W., Abrham, Y. T., Bucklaew, A., Mitchell, J. F. Abstract: During natural visual foraging, primates move their eyes 2-3 times per second to bring objects of interest to central, high-resolution vision at the fovea. For moving objects, they use a combination of rapid saccadic eye movements along with smooth following movements to track targets continuously. It is also known that saccadic eye movements produce perceptual enhancements for the saccade target before the eyes move, called pre-saccadic attention. Recently, in human participants, we found that saccades made to peripheral motion apertures resulted in smooth post-saccadic following that tracked stimulus motion at low gain (Kwon, Rolfs, & Mitchell, 2019). Because this effect persisted even when the stimulus disappeared in saccade flight, we can infer the post-saccadic following was predictive, reflecting the integration of peripheral motion information from the target before the saccade, and provides an automatic perceptual read-out of stimulus motion. Here we examined post-saccadic following in marmoset monkeys to determine if they automatically tracked stimulus motion like humans, and if so, if that following response could be used as a reliable behavioral read-out of motion. Marmosets performed a saccade foraging task in which they initially acquired central fixation and then made a saccade that sampled between three different motion apertures. For each trial, the direction of motion of each aperture was independently sampled from 16 directions. We found that immediately upon saccade offset, the marmosets eye traces followed the pre-saccadic motion with a low (10-20%) gain that was consistent with humans. We also found that the motion from other non-target apertures influenced following responses though with a much weaker gain. The gain was distributed equally across apertures before the saccade, but immediately after the saccade was enhanced for the saccade target relative to other apertures, consistent with a post-saccadic target enhancement found in smooth pursuit (Gardener and Lisberger, 2001). This following response provided an estimate of target motion with a median absolute angular errors ranging from 25 to 50 degrees across sessions, roughly half as accurate as that achieved with an explicit trained perceptual report (Cloherty et. al., 2020). Session by session the relative gain for the target as compared to other apertures also varied, providing an index of attentional selection. These findings support that natural visual foraging with moving targets can provide an automatic behavioral read-out of peripheral motion integration and pre-saccadic attention.

Abstract: Magnetic resonance imaging (MRI) is a noninvasive neuroimaging method beneficial for the identification of normal developmental and aging processes and data sharing. Marmosets have a relatively shorter life expectancy (approximately 10 years) than other primates, including, humans because they grow and age faster. Hence, the common marmoset model is effective in aging research. The current study investigated the aging process of the marmoset brain and provided an open MRI database on marmosets with a wide age range. The Brain/MINDS Marmoset Brain MRI Dataset contains brain MRI information on 216 marmosets aged between 1 and 10 years. During its release date, it is the largest public dataset worldwide. Further, it comprises multi contrast MRI images. In addition, 91 of 216 animals have corresponding ex vivo high-resolution MRI datasets. Our MRI database, which is available at the Brain/MINDS Data portal might help understand the effects of different factors, such as age, sex, body size, and fixation, on the brain. Moreover, it can contribute to and accelerate brain science studies worldwide. Copy rights belong to original authors. Visit the link for more info Podcast created by PaperPlayer

Here's what passes for science at a major U.S. university. Experiments on menopause involving animals who don't naturally experience menopause, and all intended to find treatments for menopause in humans. You don't need to be a scientist to think that doesn't make sense. And neither does the $4 million the National Institutes of Health gave a researcher at the University of Massachusetts-Amherst to do the research. PETA has filed a suit to get video and documents to expose and put a stop to the experiments. In the meantime, the wasteful experiments continue. Why do they happen? This is the way grant-funded science works in America. PETA is trying to change that with among other things the Research Modernization Deal.

Abstract: Impairments in the experience-dependent elaboration of neural circuits are assumed to underlie autism spectrum disorder (ASD). However, the phenotype underlying synaptic plasticity is poorly understood. Here, we used a valproic acid-induced ASD marmoset model and in vivo two-photon microscopy to investigate the structural dynamics of dendritic spines in the dorsomedial prefrontal cortex, which is involved in ASD core symptoms. In model marmosets compared to controls, spine turnover was upregulated and spines were actively generated in clusters. Clustered emerging spines were predominant in carryover of generated spines in the model marmosets. Presynaptic boutons of local axons, but not long-range commissural axons, showed hyperdynamic turnover. Furthermore, nasal oxytocin administration reduced the clustered emergence of spines. Finally, we confirmed the high molecular conformity of adult animal models with human ASD. Our study suggests that an altered balance between synaptic plasticity and consolidation underlies ASD, and may be a potential therapeutic target. Copy rights belong to original authors.

“In this endless discussion [about animal experimentation] we completely forget that animals are used now and they need our attention now.” - Augusto Vitale & Sabrina Brando Dr Augusto Vitale joins us to share his experience in the study of non-human primate behaviour and welfare. Since 1991 Augusto has worked as a researcher at the Istituto Superiore di Sanità in Rome (Italy) dedicating his scientific activity to investigate behaviour, cognition and welfare of non-human primates, with a focus on common marmosets used in neuroscience and biomedical research. He guides us in discovering the work of ethologists and evolutionary biologists who contributed to unveiling key aspects of animal behaviour and cognitive skills. He passionately illustrates his research on cooperation and describes how studying common marmosets' behaviour can shed light on the evolution of altruism in humans. Augusto also shares with us his work in the EU Expert Working Group responsible for creating guidelines on the protection of animals used in scientific procedures. He discusses the use of animals in experimentation, providing meaningful insight into the current legislation and ethical debate. Augusto concludes by telling us about his strong bond with animals and highlighting the importance of positive human-animal interactions for enhancing captive animal well-being.

When you first see this animal you may think it's a few animalsphotoshopped together, but it's really just one. The pygmy marmoset is native to south america. They can be foundin the rainforests of Brazil, Colombia, peru, Ecuador, and Bolivia. They spendtime hiding among the plants. They live in small groups of up to 15 others.Marmosets eat mostly insects, fruit, and tree sap. Pygmy marmosets find food by using their good climbing skills toforage in the trees. These animals are very small they have a lot of predators.Some include cats, eagles, hawks, and snakes. The way they protect themselvesis by making loud screeches and noises to scare the predator away. Pygmy marmosets are special because of their miniature size. Theyare usually about half a foot or 12 centimeters. They are one of the smallestmonkey species in the world. They have a lifespan of around 12 years, or 16 incaptivity. There are around 2,500 pygmy marmosets left in the wild. They areshaped somewhat like an egg and have brownish grey fur all over their bodies. for wild suzhou i'm palm tree and thank you for listening.

Y., Kuwako, K.-i., Okahara, J., Bae, B.-I., Okuno, M., Mashiko, H., Shimogori, T., Walsh, C. A., Sasaki, E., Okano, H. Abstract: GPR56, a member of the adhesion G protein-coupled receptor family, is abundantly expressed in cells of the developing cerebral cortex, including neural progenitor cells and developing neurons. The human GPR56 gene has multiple presumptive promoters that drive the expression of the GPR56 protein in distinct patterns. Similar to coding mutations of the human GPR56 gene that may cause GPR56 dysfunction, a 15-bp homozygous deletion in the cis-regulatory element upstream of the noncoding exon 1 of GPR56 (e1m) leads to the cerebral cortex malformation and epilepsy. To clarify the expression profile of the e1m promoter-driven GPR56 in primate brain, we generated a transgenic marmoset line in which EGFP is expressed under the control of the human minimal e1m promoter. In contrast to the endogenous GPR56 protein, which is highly enriched in the ventricular zone of the cerebral cortex, EGFP is mostly expressed in developing neurons in the transgenic fetal brain. Furthermore, EGFP is predominantly expressed in GABAergic neurons, whereas the total GPR56 protein is evenly expressed in both GABAergic and glutamatergic neurons, suggesting the GABAergic neuron-preferential activity of the minimal e1m promoter. These results indicate a possible pathogenic role for GABAergic neuron in the cerebral cortex of patients with GPR56 mutations. Copy rights belong to original authors. Visit the link for more info

Abstract: We introduce a straightforward, robust method for recording and analyzing spiking activity over timeframes longer than a single session, with primary application to the marmoset (Callithrix jacchus). Although in theory the marmoset's smooth brain allows for broad deployment of powerful tools in primate cortex, in practice marmosets do not typically engage in long experimental sessions akin to rhesus monkeys. This potentially limits their value for detailed, quantitative neurophysiological study. Here we describe chronically-implanted arrays with a 3D arrangement of electrodes yielding stable single and multi- unit responses, and an analytic method for creating "supersessions" combining that array data across multiple experiments. We could match units across different recording sessions over several weeks, demonstrating the feasibility of pooling data over sessions. This could be a key tool for extending the viability of marmosets for dissecting neural computations in primate cortex. Copy rights belong to original authors. Visit the link for more info

Abstract: The common marmoset (Callithrix jacchus) is a small-bodied New World primate that is becoming an important model to study brain functions. Despite several studies exploring the somatosensory system of marmosets, all results have come from anesthetized animals using invasive techniques and post-mortem analyses. Here we demonstrate the feasibility for getting high-quality and reproduceable sensorimotor mapping in awake marmosets with functional magnetic resonance imaging (fMRI). We acquired fMRI sequences in four animals while they received tactile stimulation (via air-puffs), delivered to the face, arm or leg. We found that the body representation progressed medially from the leg to the face in areas 3a, 3b, 1/2, and from caudal to rostral sites in areas S2 and PV. SI and SII exhibited a body representation in their functional connectivity pattern within the posterior and midcingulate and the thalamus. Interestingly, we also found a somatotopic body representation in two subcortical areas: the thalamus and, for the first time, in the putamen. These maps have similar organizations as those previously found in Old World macaque monkeys and humans, suggesting that these subcortical somatotopic organizations were already established before Old and New World primates diverged. Our results show the first whole brain mapping of somatosensory responses acquired in a non-invasive way in awake marmosets. Copy rights belong to original authors. Visit the link for more info

S., Everling, S. Abstract: Understanding the similarity of cortico-subcortical networks topologies between humans and nonhuman primate species is critical to study the origin of network alternations underlying human neurological and neuropsychiatric diseases. The New World common marmoset (Callithrix jacchus) has become popular as a non-human primate model for human brain function. Most marmoset connectomic research, however, has exclusively focused on cortical areas, with connectivity to subcortical networks less extensively explored. In this study, we aimed to first isolate patterns of subcortical connectivity with cortical resting-state networks (RSNs) in awake marmosets using resting-state functional magnetic resonance imaging (RS-fMRI), then to compare these networks to those in humans using connectivity fingerprinting. While we could match several marmoset and human RSNs based on their functional fingerprints, we also found a few striking differences, for example strong functional connectivity of the default mode network with the superior colliculus in marmosets that was much weaker in humans. Together, these findings demonstrate that many of the core cortico-subcortical networks in humans are also present in marmosets, but that small, potentially functionally relevant differences exist.

Marmosets are small New World monkeys from South America. © Clem Spalding 210-271-7273 Marmosets are a useful biomedical research animal model that is growing in popularity with researchers. The monkeys' small size and shorter life span make it an easier model to work with, in some cases, than larger nonhuman primates. Texas Biomed currently has more than 350 of these squirrel-sized monkeys. UT Health San Antonio and the Sam and Ann Barshop Institute for Longevity and Aging Studies have just signed an animal care and joint research agreement with Texas Biomed. The new collaboration involved moving dozens of marmosets from the UT Health campus into a newly-renovated facility that is part of the Southwest National Primate Research Center on the Texas Biomed campus. The new home for marmosets can house up to 550 of the research animals, making it the largest marmoset colony in the U.S. dedicated to aging and infectious disease research. Corrina Ross, Ph.D. Associate Professor Corinna Ross, Ph.D., talks about the projects these animals are involved with and the challenges researchers face when trying to find answers to complex human health questions.

For wildlife photographer Paul Ojuara, getting the perfect shot in Natal, on Brazil’s northeastern tip, can be an extreme sport. Paul’s hometown can be violent (to get to some areas, wildlife photographers need police escorts), and the animals themselves can be a little tricksy (prowling pumas, anyone?). But for architect-turned-biologist Paul, these challenges just fuel his passion for wildlife, in particular the common marmosets and burrowing owls he’s been photographing locally for years. In this episode of Wild Lives By Faunographic, Paul shares what he’s learnt from his daily encounters with these stunning creatures, reveals the surprising challenges they face and explains the stories behind his most iconic photos.

Marmosets in the study were monitored with Fitbit-like devices. What does a monkey wearing a Fitbit-like device have to do with Parkinson's disease? A newly-published study shows marmosets at the Southwest National Primate Research Center can mimic the non-motor symptoms of Parkinson's. Marmosets are small, New World monkeys that can mimic the sleep disturbances, changes in circadian rhythm, and cognitive impairment people with Parkinson's disease develop. Associate Scientist Marcel Daadi, Ph.D., leader of the Regenerative Medicine and Aging Unit at the SNPRC, is the lead author of a new study published in the journal PLOS ONE. In addition to monitoring the marmosets, scientists videotaped the animals to document their ability to perform certain tasks and how those abilities were impacted over time by the disease. By developing an effective animal model that can emulate both the motor and non-motor symptoms of Parkinson’s disease, scientists have a better chance of understanding the molecular mechanisms of the neuro-circuitry responsible for changes in the brain during the course of the disease. Scans like magnetic resonance imaging (MRIs) and analysis after dissections may lead to potential targets for new therapies for patients.  

The Southwest National Primate Research Center at Texas Biomedical Research Center is one of only two national primate research centers that provide marmoset research resources. Our resources include the only large population (>70) of aged marmosets (>10 years) in the country. Common marmosets have been a biomedical research resource since the early 1960’s, used predominately in studies of infectious disease, immunology and neuroscience.  Historically, they have been a more commonly used research model in Europe and Japan than in the United States. However, cellular and molecular resources have recently been developed that greatly enhance the value of marmosets in research and have increased interest here in the United States. As a non-endangered anthropoid primate with small size, the highest fertility and the shortest life span, marmosets also offer a remarkably cost-effective, high efficiency nonhuman primate model for biomedical research. In addition, many areas of research take advantage of unique features of its biology for application to human disease. They’re closely related to humans, but marmosets also have unique features that make them particularly valuable for certain types of studies. For example, marmosets have small body size, usually produce dizygotic twins, mature quickly, have the highest fertility of any anthropoid primate and have a short life span. Our marmoset resources have achieved notable accomplishments in genomics, regenerative medicine, obesity, aging and reproduction research. © Clem Spalding 210-271-7273

Geoff Butcher has Parkinson's disease. Here we hear him interview a scientist who uses Marmosets as an animal model to investigate Parkinson's disease. The scientist does this by using a chemical called MPTP to destroy the substantia nigra in the Marmosets. This is the part of the brain that is associated with the fine control of movement. It is damage to the substantia nigra that caused the symptoms of Parkinson's disease. The discovery of MPTP was an accident. Drug-users took contaminated material and developed Parkinsonian-like symptoms. This led to the unravelling of a medical mystery described in The Case of The Frozen Addicts reviewed here: http://www.nejm.org/doi/full/10.1056/NEJM199612263352618
