People with autism have more gray matter — or neuronal matter — in their brains overall than their typical peers do.

Girls and boys with autism show different patterns of brain activity in response to sensory stimuli.

A transparent set of electrodes enables researchers to simultaneously record electrical signals and visualize neurons in the brains of awake mice.

In autism research, as in other fields, small sample sizes can lead to false findings. The size of the sample needed for statistical significance depends on the type of study.

A new map shows three brain networks that govern social communication in rhesus macaques.

The brain’s system for sensing pleasure and reward shows unusual activation patterns and an atypical structure in people with autism.
