Scientists find molecular player in Angelman syndrome
Two independent teams have discovered key molecular steps in the way a single gene disrupts the connections between neurons in individuals with Angelman syndrome. Because the gene, UBE3A, has also been linked to autism, the findings could help scientists understand and treat a range of neurodevelopmental disorders.

Postmortem brains point to impaired inhibition in autism
Researchers have found a higher density of several types of interneurons — nerve cells that connect sensory and motor neurons in the brain— in postmortem brain tissue from individuals with autism, compared with healthy controls. The findings appear in the February issue of Acta Neurologica Scandinavica.

Loss of inhibitory neurons marks autism mouse models
Autism may be the result of faulty wiring that occurs during early brain development, according to two independent studies that looked at the origins of circuit disruption.

Autism marked by altered trajectory of brain growth
Although the head overall is bigger in some children with autism, researchers have found more informative differences in size — some smaller, some larger — across regions of the brain.

Eye-tracking brings focus to ‘theory of mind’
People with Asperger syndrome don't automatically show 'theory of mind', the ability to understand the desires and beliefs of others, according to a report published 16 July in Science. Instead, they seem to use deliberate reasoning to understand social behaviors, learned after years of practice in the real world. Watch the video

Coding bonus: Bats’ hippocampal cells log spatial, social cues
The neurons represent not only an animal’s place in space, but also the distinguishing features of its fellow bats, including their sex and social status.

New human brain atlas charts gene activity and chromosome accessibility, from embryo to adolescence
The resource profiles millions of single cells across the developing cortex, revealing when, where and how certain cell types emerge and illuminating possible origins of autism and other conditions.
