The use of stone tools by macaques in Thailand has reduced the size and population density of coastal shellfish; previously it was thought that tool-assisted overharvesting effects resulted uniquely from human activity.
Tool behaviour of long-tailed macaques leaves archaeological signatures that differ between populations despite similar ecological conditions, highlighting the potential for diversity in material culture.
The multiple component mechanisms of extra-classical receptive field modulation, with distinct dynamics, discovered in the monkey visual cortex have important implications for understanding contextual perceptual processing.
Lipocalin-2 is a strong predictor of hunger scores, reflects an anti-obesity response that is deregulated in severely obese subjects, and exerts an anorexigenic function with a conserved interspecies mechanism.
A hub in the rostral anterior cingulate cortex receives unusually high and functionally diverse inputs, providing a biological interface between motivation, incentive based learning, and decision making.
Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.
