Enriched environment staves off autism-like behavior in rats

by  /  20 November 2014

Rats exposed in utero to the epilepsy drug valproic acid, a risk factor for autism, do not develop autism-like behaviors if they are reared in a stimulating environment. Researchers presented the unpublished findings yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Mutation boosts paternal age’s autism-like effects in mice

by  /  19 November 2014

Mice born to older males with mutations in PAX6 — a gene involved in brain development — vocalize less than those with younger dads. The unpublished findings, presented today at the 2014 Society for Neuroscience annual meeting in Washington, D.C., suggest how genes and paternal age can work together to trigger symptoms.

Fond caresses, loving squeezes shape social brain

by  /  19 November 2014

Soft touch and physical closeness to other people wire the social brain right from the earliest days after birth, and problems in the response to touch may play a fundamental role in autism. This picture emerges from unpublished results presented by several teams at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Cesarean birth alters immune system, social behavior in mice

by  /  18 November 2014

Mice born via cesarean section show subtle social deficits and increased immune and stress responses, suggesting a link between microbe exposure during birth and behavior. Researchers presented the unpublished work today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Tadpole model links epilepsy drug’s effects to chromatin

by  /  16 November 2014

Valproic acid, an epilepsy drug that increases the risk of autism, may alter neural circuits by opening up chromatin, a tightly packaged form of DNA in the nucleus. Researchers presented the unpublished data today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.
