Your expectations shape and quicken your perceptions. A new model that explains how that happens also suggests it’s time to update theories about sensory perception and decision making.

Neuroscience has found that gestures are not merely important as tools of expression but as guides of cognition and perception.

To make headway on the mystery of consciousness, some researchers are trying a rigorous new way to test competing theories.

The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.

Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.

A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations.

In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.

A technique based on genetic bar codes can easily map the connections of individual brain cells in unprecedented numbers. Unexpected complexity in the visual system is only the first secret it has revealed.

Using a brain-computer interface, scientists are beginning to learn why learning is hard.
