Molecular mechanisms: Autism gene modulates connectivity

by  /  10 April 2012

Neurons lacking PTEN, an autism-associated gene also involved in cancer, are hyperconnected to both near and distant brain cells, according to a study published 1 February in The Journal of Neuroscience.

Cognition and behavior: Brain changes tied to autism severity

by  /  16 March 2012

Adults with autism have regional differences in brain volume in areas that play a role in social behavior and communication compared with controls, according to a large study published in the February issue of Archives of General Psychiatry. The differences correlate with the severity of autism symptoms, the study also shows.

Cognition and behavior: Autism brains have abnormal links

by  /  9 September 2011

The brains of boys with autism have a lower-than-normal rate of water diffusion across the inferior fronto-occipital fasciculus — a bundle of neurons that connects all four major lobes of the brain, according to a new study.
