Molecular mechanisms: Maternal infection linked to schizophrenia in mice

by  /  9 November 2010

Infection early in pregnancy is more harmful to the fetus than at later stages, triggering brain and behavioral changes in the offspring similar to those seen in people with schizophrenia, according to two mouse studies published in October. A third study suggests that exercise can mitigate some of these effects.

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.

Variants in trust hormone receptor up the risk for autism

by  /  1 February 2010

Genetic variations that tweak the brain’s release of oxytocin — a hormone involved in social bonding and establishing trust — may increase the risk of developing autism or traits of the disorder, according to three new studies published in the past few months.
