Mouse lines light up the brain’s off switch

by  /  16 November 2011

Researchers have engineered 20 mouse lines that allow them to manipulate genes in specific neuronal circuits. The resource, reported 22 September in Neuron, will allow researchers to better explore the role of interneurons, which dampen signals in the brain, in mouse models of autism.
