In a video interview at the 2011 Society for Neuroscience annual meeting in Washington, D.C., Caroline Blanchard describes some of the unusual behaviors that suggest that the BTBR mouse is a good model for autism.

Drugs that act on the adrenaline system can alleviate autism-like symptoms in a rat model of the disorder, according to unpublished research presented Sunday in Washington, D.C.

Mice with a mutation in the Rett syndrome gene are more social than controls, according to a study published 11 September in Behavioral Genetics. The results, based on detailed observation of social behavior, support previous studies showing that Rett syndrome mouse models do not have severe social deficits.

A protein involved in the cascade of interactions at the junctions between neurons points to a potential therapy for fragile X syndrome, according to unpublished data presented at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

The fragile X protein FMRP helps make proteins at the synapse, the junction between neurons, even when the genetic instructions for doing so are located far away in the nucleus, says Kimberly Huber.

In a Nature commentary, Laurent Mottron, professor of psychiatry at the University of Montreal, argues that autism is not a defect that needs fixing.

Connections between the amygdala — a deep nub involved in processing emotions — and other parts of the brain are more numerous in children than in adults, according to unpublished research presented at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

Scientists are analyzing more than 7,000 studies of functional magnetic resonance imaging to refine the role of various regions in the brain, according to unpublished work presented Monday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

Mice that have an excess of the Rett syndrome protein MeCP2 have biochemical and neuronal characteristics that are strikingly similar to those of mice that completely lack the protein, according to unpublished research described Sunday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

By focusing on recessive mutations inherited from both parents, researchers have identified 50 new candidate genes for intellectual disability.
