title: Brain disorders: getting 'Down' to the gene.
abstract: Narrowing down the genetic basis of Down syndrome, in which hundreds of genes are triplicated, has been difficult. A new study finds that the expression of two affected genes, Olig1 and Olig2, is critical for maintaining the balance of inhibitory and excitatory signaling in a mouse model of Down syndrome.
