Injecting cells called interneurons into the brains of a mouse model of autism restores typical social behavior. But the reason for this effect is a puzzle.

Loss of certain neurons on one side of the brain may explain why some autistic people are hypersensitive to touch.

Forecasts for this year’s Nobel Prizes include several researchers whose work is relevant to autism.

An analysis of four mouse models negates certain assumptions underlying the signaling imbalance theory of autism.

A brain region that orchestrates responses to social cues and aids decision-making may be off tempo in autism.

Lattice-like structures that surround neurons may be overly abundant — or scarce — in brain regions of three autism mouse models.

Male monkeys that avoid touching, grooming or playing with others have low brain levels of the hormone vasopressin.

Mice lacking CNTNAP2, a gene strongly linked to autism, are acutely sensitive to pain.
