Mouse models point to early troubles in tuberous sclerosis

by  /  28 November 2011

The brain abnormalities characteristic of tuberous sclerosis may begin early in development and involve malfunctioning of neuronal precursors, according to studies of two different mouse models of the disorder published in October.

A case for the importance of interneurons in autism

by ,  /  22 November 2011

The etiology of autism may be best understood as an impairment of neuronal circuits, specifically interneurons that dampen signals in the brain, says neuroscientist Gordon Fishell.

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.

Subset of Rett gene’s targets may lead to the disorder

by  /  14 November 2011

Deleting the Rett syndrome gene in a subset of neurons, instead of throughout the body, dramatically lowers the number of genes that are dysregulated in those neurons, according to results presented in a poster session Saturday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

Vision problems in Rett syndrome could serve as biomarker

by  /  13 November 2011

Mice missing the Rett syndrome gene MeCP2 show a gradual decline in vision, and too much inhibitory signaling in the visual cortex, according to unpublished research presented Thursday in Washington, D.C.

New mouse model mimics many symptoms of autism

by  /  3 October 2011

Mice lacking the autism-linked gene CNTNAP2 show many of the behaviors associated with the disorder, and exhibit brain circuit disruptions similar to those seen in people who carry mutations in the gene.

Molecular mechanisms: Dopamine implicated in Rett syndrome

by  /  13 September 2011

Loss of MeCP2, the Rett syndrome gene, in neurons that release the chemical messenger dopamine may lead to the motor deficits associated with the syndrome.
