Humans scale brain signal variability with stimulus complexity to efficiently process visual inputs, an ability reduced in those with poorer visual discrimination and in older adults with lower GABA levels (brain's major inhibitory neurotransmitter), but recoverable by boosting GABA pharmacologically.

Fruit flies detect cholesterol through ionotropic receptors in taste, leading to active avoidance despite dietary necessity.

Genetic tools were generated and used to determine the neurotransmitters and neuropeptides used by individual cell types within the Drosophila central complex and to study their roles in sleep regulation.

Understanding and reasoning about the physical world rely on a specific brain network, in which the area PF of the left inferior parietal lobe plays a central role.

A game-theoretical framework for uncovering how optimal signal transmission takes place in a given network, here applied to large-scale brain networks.

Putative markers of VTA interneurons label VTA projection neurons, and VTA projection neurons make intra-VTA synapses, suggesting VTA projection neurons may mediate functions prior attributed to interneurons.

Future prosocial acts can be forecasted from stable biological differences in how people perceive others' merit, pointing to novel strategies to reduce favoritism and discrimination in social situations.
