Pups born to pregnant mice infected with a mock virus are known to show changes in their immune system. These effects may in turn impair proper brain signaling, according to results presented Saturday at the 2013 Society for Neuroscience annual meeting in San Diego.

A rare condition marked by a sudden and profound loss of skills is biologically distinct from other forms of autism.

A brain circuit that controls movement is altered in people with autism, a postmortem brain study suggests.

A new method for examining blobs of neurons known as ‘mini-brains’ reveals structures like those in the human brain.

A minority of boys with autism have brains that are unusually large relative to their bodies — a trait tied to regression and intellectual disability.

‘Mini-brains’ created in a dish may reveal autism’s roots and point to treatments, but they do not yet mirror some critical features of a human brain.

The brains of some women with autism more closely resemble those of typical men than those of typical women.

The faster the brains of children with autism grow in their first year of life, the more severe their autism features are likely to be at age 2.

The brains of people with autism show a distinct molecular signature that reflects alterations in how genes are pieced together and expressed.

The brains of many people with autism may exhibit a characteristic arrangement of chemical groups on the proteins that DNA coils around.
