Autism is predominantly genetic in origin, but a growing list of prenatal exposures for mother and baby may sway the odds.
Lattice-like structures that surround neurons may be overly abundant — or scarce — in brain regions of three autism mouse models.
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.
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.
