Neural stem cells derived from people with Rett syndrome show early signs of dysfunction, according to unpublished research presented at the 2012 Society for Neuroscience annual meeting.

Mice missing the autism-linked gene CNTNAP2 have broad defects in their oxytocin system, according to research presented Tuesday at the Society for Neuroscience annual meeting in New Orleans. Treatment with oxytocin alleviates social deficits in these mice.

A cholesterol-lowering drug called lovastatin prevents seizures in mice that model fragile X syndrome, according to a poster presented Sunday at the 2012 Society for Neuroscience annual meeting in New Orleans.

Treatment with a single bacterial species curbs anxiety and repetitive behaviors and boosts vocalizations in a mouse model of autism, according to a poster presented Monday at the 2012 Society for Neuroscience annual meeting in New Orleans.

Rapid progress in gene discovery and an emerging map of the molecular landscape of normal brain development are presenting unprecedented opportunities to unravel the biology of autism spectrum disorders, say Matthew State and Nenad Sestan.

Mouse studies of a promising treatment for Rett syndrome, already in clinical trials, offer a note of caution about the drug’s potential. Preliminary findings from the research, presented Sunday at the Society for Neuroscience annual meeting in New Orleans, show why mouse work remains important even after clinical trials are underway.

Researchers are testing a wealth of new treatments for fragile X syndrome, an inherited intellectual disability often accompanied by autism. They presented preliminary results from animal studies of several drugs, as well as an automated approach for screening compounds, Sunday at the 2012 Society for Neuroscience annual meeting in New Orleans.

The anxiety drug diazepam, commonly marketed as Valium, reverses deficits in sensory integration in a mouse model of autism, according to research presented Sunday at the Society for Neuroscience annual meeting in New Orleans.

A small pilot study suggests that the drug propranolol, typically used to treat hypertension and anxiety, enhances functional connectivity between brain regions and improves verbal fluency, according to research presented Saturday at the 2012 Society for Neuroscience annual meeting in New Orleans.

Star-shaped cells in the brain wrap themselves around synapses, the junctions between neurons, and influence their development. In a video interview Saturday at the 2012 Society for Neuroscience annual meeting in New Orleans, Ben Barres discusses the possible role of astrocytes in autism.
