The brains of rats exposed in utero to the seizure drug valproate show a significant increase in brain size around the time of birth.

New results from brain scans of adults with autism are at odds with the popular theory that the condition involves weak brakes on brain activity.

Two new methods for building ‘mini-brains’ may help researchers study how early brain development differs in people with autism.

Looking at the brain as a whole suggests that nudging flawed sets of neurons to collaborate better might alleviate autism traits.

Genes linked to autism are critical to the development of star-shaped brain cells called astrocytes, suggesting a key role for the cells in the condition.

A fusion of two existing drugs alleviates autism-like features in a mouse model of the condition.

Neurons derived from people with mutations linked to autism display diverse abnormalities that may help explain the origins of these individuals’ features.

A widely used treatment for anxiety can eliminate some of the cognitive and social problems seen in mice missing a copy of ARID1B, a gene associated with autism.

Music therapy proves ineffective for autism, brain structures differ with 16p11.2 duplications and deletions, and mice missing NLGN3 may influence the sociability of their littermates.

Turning on a set of neurons that dampen brain activity improves social behavior in a mouse model of autism; turning off neurons that excite brain activity does the same thing.
