Research in primate brains has been essential for the development of BCIs, ANNs. New funding and policy changes put future such advances at risk.

Ozempic, MRI machines and flat screen televisions all emerged out of fundamental research decades earlier — the very types of study being slashed by the US government.

Here, the authors created a virtual reality task for monkeys and mice to explore if internal states like attention are similar across species. Their facial expressions during the task were similar, su...

Metacognition is the process of reflecting on and controlling one's own thoughts and behaviors. Metacognitive ability is often measured through modeling the relationship between confidence reports and...

Synchrony between neuronal activity and the respiratory cycle has been observed in numerous brain regions and across many species. Tort et al. discuss the mechanisms by which brain activity is modulat...

Neural firing-rate responses to sensory stimuli show progressive changes both within and across sessions, raising the question of how the brain mainta…

Nature Reviews Neuroscience - Sub-additive responses to simultaneously presented stimuli and quenching of variability in responses to repeated presentations of a stimulus are characteristics of...

Movements that boost activity in the visual cortex of mice have the opposite or no effect in marmosets and macaques, prompting questions about whether mice are a suitable model for the primate visual…

Perceptual judgments of the environment emerge from the concerted activity of neural populations in decision-making areas downstream of the sensory...

Identifying the psychological and neurobiological processes underpinning intra-individual variations in choice behaviour presents a formidable challenge. In this Review, Duffy et al. discuss how algor...

Recent studies in non-human primates do not find pronounced signals related to the animal’s own body movements in the responses of neurons in the visual cortex. This is notable because such pronounced signals have been widely observed in the visual cortex of mice. Here, we discuss factors that may contribute to the differences observed between species, such as state, slow neural drift, eccentricity, and changes in retinal input. The interpretation of movement-related signals in the visual cortex also exemplifies the challenge of identifying the sources of correlated variables. Dissecting these sources is central for understanding the functional roles of movement-related signals. We suggest a functional classification of the possible sources, aimed at facilitating cross-species comparative approaches to studying the neural mechanisms of vision during natural behavior.

Animals capable of complex behaviors tend to have more distinct brain areas than simpler organisms, and artificial networks that perform many tasks tend to self-organize into modules (1-3). This sugge...
