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

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.

After more than a decade of effort, scientists are questioning whether mouse models of autism can ever capture the social deficits seen in people with the condition.

Exposure to certain types of light at night may exacerbate sleep issues among people with autism.

Problems with social interactions stem from faulty wiring of a single circuit spanning distant brain regions, results from three mouse models of autism suggest.

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.

Exposure to a dim light at night disrupts sleep and worsens repetitive behaviors and social difficulties in a mouse model of autism.

The absence of an autism-linked gene, combined with exposure to a mock infection, produces social deficits in mice — but only in males.

Conventional wisdom holds that people with autism don’t get hooked on alcohol or other drugs, but new evidence suggests otherwise.
