Deletion and duplication of the 16p11.2 chromosomal region have opposite effects on brain size, but produce similar alterations in the brain’s processing of sound. Researchers reported these and other unpublished findings at the 2013 Society for Neuroscience annual meeting in San Diego, painting a complex picture of the region’s role in autism.

Rat models of autism have a weak and sluggish brain response to speech sounds, but behavioral training can improve their performance. The unpublished results, presented Sunday at the 2013 Society for Neuroscience annual meeting in San Diego, suggest that a similar approach may benefit people with the disorder.
The brains of children with autism don’t tune out irrelevant sensory information, according to a brain imaging study presented Saturday at the 2013 Society for Neuroscience annual meeting in San Diego.
Children who carry an extra copy of the 15q11-13 region of the genome usually have autism and sleep troubles, as well as distinctive brain-wave patterns and facial features, according to a report published 14 March in Autism Research.
People with autism are adept at detecting whether two items appear on a screen simultaneously or close together in time, according to a study published 14 December in the Journal of Autism and Developmental Disorders.
Connections between neighboring groups of brain cells are weaker in individuals with autism than in controls, according to a report published 14 January in the Proceedings of the National Academy of Sciences.
Husband and wife research team Andrew Meltzoff and Patricia Kuhl have shown that learning is a fundamentally social process, beginning in early infancy.
