Home-enclosure-based behavioral and wireless neural recording setup for unrestrained rhesus macaques

Electrophysiological studies with behaving nonhuman primates often require the separation of animals from their social group as well as partial movement restraint to perform well-controlled experiments. When the research goal per se does not mandate constraining the animals' movements, there...

Trends and treatment approaches for complications in neuroscience experiments with monkey species

Our goal in this manuscript is to advance the assessment and treatment of monkey species in neuroscience research. We hope to begin a discussion and establish baseline data on how complications are identified and treated. We surveyed the neuroscience research...

Urinary cytokine measurements do not reflect surgery-induced inflammation in rhesus macaques

Measurement of the health and disease status of free-ranging primates is often limited by a lack of available biomarkers of immune activation and inflammation that can be applied noninvasively via the measurement of urine or fecal samples. Here, we evaluate...

Monkeying around: Non-human primate behavioural responses to humans reproducing their facial expressions

People are often observed mimicking animals' facial expressions in an attempt to communicate with them. However, to date, there is limited understanding of how animals respond to humans reproducing their facial displays, or if this type of human behaviour presents...

The four Cs of psychological wellbeing: Lessons from three decades of computer-based environmental enrichment

Three decades ago, the Animal Welfare Act was amended to require researchers to provide environments that promoted the psychological, as well as the physical, wellbeing of nonhuman primates maintained for research purposes. We developed a computer-task paradigm with the goal...

Psychosocial stress alters the immune response and results in higher viral load during acute simian immunodeficiency virus infection in a pigtailed macaque model of human immunodeficiency virus

Although social distancing is a key public health response during viral pandemics, psychosocial stressors, such as social isolation, have been implicated in adverse health outcomes in general [1] and in the context of infectious disease, such as human immunodeficiency virus...

Promoting good nonhuman primate welfare outside regular working hours

Promoting good primate welfare outside of daylight hours is an important task. The responsibility to provide a complex environment and environmental enrichment is an essential element of primate wellbeing programs that should be approached from a 24-h perspective and planned...

Investigating subtle changes in facial expression to assess acute pain in Japanese macaques

Changes in facial expression provide cues for assessing emotional states in mammals and may provide non-verbal signals of pain. This study uses geometric morphometrics (GMM) to explore the facial shape variation in female Japanese macaques who underwent experimental laparotomy. Face...

Social housing status impacts rhesus monkeys’ affective responding in classic threat processing tasks

Individuals' social contexts are broadly recognized to impact both their psychology and neurobiology. These effects are observed in people and in nonhuman animals who are the subjects for comparative and translational science. The social contexts in which monkeys are reared...

Harmonisation of welfare indicators for macaques and marmosets used or bred for research

Background: Accurate assessment of the welfare of non-human primates (NHPs) used and bred for scientific purposes is essential for effective implementation of obligations to optimise their well-being, for validation of refinement techniques and novel welfare indicators, and for ensuring the...
