Marmoset

Validation of body condition scoring as a screening test for low body condition and obesity in common marmosets (Callithrix jacchus)

Assessing body weight is common practice for monitoring health in common marmosets (Callithrix jacchus). Body composition analysis via quantitative magnetic resonance (QMR) is a more in-depth assessment allowing measurements of lean and fat mass, but it is expensive and remains...

Marm-ite moments: Enriching marmoset behaviour with the 3Rs

It is well documented that activity levels of non-human primates (NHPs) are reduced in captivity, particularly in laboratory settings where space and enclosure design are limited.1 The 3Rs encourages researchers to refine their care of protected species by increasing the...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Minimally invasive electrocorticography (ECoG) recording in common marmosets

Background: Electrocorticography (ECoG) provides a valuable compromise between spatial and temporal resolution for recording brain activity with excellent signal quality, crucial for presurgical epilepsy mapping and advancing neuroscience, including brain-machine interface development. ECoG is particularly effective in the common marmoset...

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...
