Development of a non-invasive novel individual marmoset holder for evaluation by awake functional magnetic resonance brain imaging

Background: Although functional MRI (fMRI) in awake marmosets (Callithrix jacchus) is fascinating for functional brain mapping and evaluation of brain disease models, it is difficult to launch awake fMRI on scanners with bore sizes of less than 16 cm. A universal...

A computational model to support the welfare-based management of a laboratory colony of common marmosets

Here, a computational model to forecast the population dynamics of a laboratory colony of common marmosets (Callithrix jacchus) is presented. This tool supports decision-making that seeks to maximize welfare and maintain a healthy and genetically diverse colony. The model considers...

Comparison of different formulations of extended-release buprenorphine in perioperative pain management in common marmosets (Callithrix jacchus)

Common marmosets (Callithrix jacchus) are increasingly used in biomedical research and often undergo surgery as part of IACUC-approved protocols. Therefore, pain control is essential to their clinical management and welfare. Extended-release buprenorphine is a valuable opioid analgesic option, as it...

A metric-based, meta-analytic appraisal of environmental enrichment efficacy in captive primates (2025)

Non-human primates (hereafter ‘primates') constitute a common group of animals in captivity but their captive maintenance involves ethical and husbandry issues, many of which can be addressed through environmental enrichment (hereafter ‘enrichment'). Enrichment is often applied in a trial-and-error fashion...

Home-cage training for non-human primates: an opportunity to reduce stress and study natural behavior in neurophysiology experiments (2025)

Research involving non-human primates remains a cornerstone in fields such as biomedical research and systems neuroscience. However, the daily routines of laboratory work can induce stress in these animals, potentially compromising their well-being and the reliability of experimental outcomes. To...

A systematic review of the effects of musical enrichment on captive mammals (2025)

Forty two studies examining physiological, behavioural and cognitive mammalian responses to music were identified, with 38.1% of those studies focusing on primates. The studies identified included 23 mammalian species across six animal orders (Artiodactyla, Carnivora, Perissodactyla, Primates, Proboscidea and Rodentia)....

Update on current hormonal and non-hormonal contraceptive options in non-human primates

Reproductive success in captive non-human primates (NHPs) has increased the demand for safe, effective, and reversible population control methods. This review provides an overview of the current literature on hormonal and non-hormonal contraceptives as reproductive control methods in NHPs. Where...
