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

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

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.

Mapping the effects of autism mutations on mouse brain circuits may reveal subtypes of the condition in people.

A technique called intracranial electroencephalography can reveal brain functions with great sensitivity and may ultimately unearth the underpinnings of autism.

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.

Machine-learning holds the promise to help clinicians spot autism sooner, but technical and ethical obstacles remain.

Grouping people with autism based on their unique brain-activity ‘fingerprints’ may help to identify subtypes of the condition.
