Surplus of neurons spurs autism traits in mice

by  /  15 January 2015

Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.
