Atypical patterns of neuronal activity and gene expression in the striatum may characterize autism in girls, according to a new study.

Autistic boys and men show notable differences in brain development, according to magnetic resonance imaging scans taken over a 16-year period.

Children with highly folded and curved brains in utero tend to show autism-linked behaviors at 18 months of age, according to a longitudinal brain-imaging study.

A technique that expands tissue before spotting and sequencing RNA — the molecular messenger for DNA — enables researchers to see where particular genes are expressed in cells.

An imaging approach that captures spheres of brain cells in three dimensions could illuminate processes in early brain development.

Welcome to the Null and Noteworthy newsletter, a roundup of papers that do the vital work of reproducing a previous result or reporting the absence of one.

A growing body of evidence shows that brain cells called oligodendrocytes may play a larger role in autism than previously thought.
