Children who have autism and their healthy siblings share patterns of brain activity that are different than those seen in children with no family history of the disorder, according to unpublished research presented at the IMFAR 2010 conference in Philadelphia.

Charting the structure and function of the brain’s many circuits may unravel autism’s mysteries.
Brain imaging reveals distinct signatures in the language circuits of young toddlers with autism while they sleep, according to unpublished data presented yesterday at the IMFAR 2010 meeting in Philadelphia.
Children with Williams syndrome — a rare genetic disorder that leads to mental retardation and overt friendliness — hold stereotypes based on gender, but not race, according to a report published in Current Biology. Because those with Williams syndrome don’t have social fear, the study suggests racial stereotypes are based partly on fear.
Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.
Mirror neurons, which fire when someone either performs an action or observes it, are not defective in people with autism, scientists report today in Neuron. The findings dispute the theory that flaws in the mirror neuron system give rise to the disorder.
Some brain areas involved in speech are larger and some smaller in children with autism compared with healthy controls, according to a series of imaging studies conducted by a Boston research group.
