‘Spiny mice’ model risk of autism from maternal infection

by  /  10 October 2012

The so-called ‘spiny mouse’ species has a gestational period twice as long as that of typical laboratory mice. This makes them good models for studying the link between prenatal exposure and autism risk, according to a study published 29 August in Brain, Behavior and Immunity.
