The fish species is separated from mammals by hundreds of millions of years of evolution, yet its seemingly primitive brain can handle many of the same elaborate visual tasks.

A new study reveals a network of neurons that, when disrupted, impairs adaptation to new circumstances in several types of dementia.

In Chapter 1, “On Being,” author Antonio Damasio outlines the dawn of consciousness.

The idea that minds and consciousness might be generated by the nervous system alone is false.

Research in recent decades has explored how animals other than humans perceive different numbers of objects

Researchers use optical illusions to investigate canine perception.

In a first-of-its-kind study, researchers monitored subsecond changes in levels of the neurotransmitters in the human brain, unlocking new insight into their function.

Using optogenetics, scientists have simulated the sense of smell directly within the mouse brain to investigate the nature of olfactory perception.

The glia seem to make up part of a newly described sensory organ, the discoverers suggest.

Carbon dioxide pumped into a bright chamber mimics a breathing host for the pest to target.

The brain wiring behind scent processing seems to scale across mammalian species.

Advanced single-cell optogenetic tools have enabled researchers to induce a learned behavior in mice without the associated visual cue.
