Faulty connectivity found in mouse model of schizophrenia

by  /  18 June 2010

Mice engineered to carry a well-known risk factor for schizophrenia show disruptions in the connections between two brain regions that coordinate memory and learning. And these disruptions directly cause problems with working memory — the ability to actively hold information and to recall that information to make a decision, according to a study published in Nature.

Studies challenge link between premature birth and autism

by  /  8 March 2010

The proposed connection between premature birth and autism may be more complicated than it seems, according to a new report. Early birth may not cause classically defined autism but, rather, may predispose children to autism-like symptoms that are part of a larger syndrome, the researchers say.

CNTNAP2 variants alter brain connectivity

by  /  19 October 2009

Adolescents who carry certain common variants in a gene associated with autism — whether they have the disorder or not — show abnormal connectivity between brain regions, according to unpublished data presented at the Society for Neuroscience meeting in Chicago.
