Molecular mechanisms: Extra MeCP2 affects brain signaling

by  /  30 March 2012

Mice with an extra copy of MeCP2, the Rett syndrome gene, have impaired signaling between neurons in the hippocampus, a brain region that plays an important role in memory, according to a study published 29 February in The Journal of Neuroscience.

Imaging study reveals insula disruption in Williams syndrome

by  /  15 March 2012

A detailed brain imaging study of people with Williams syndrome, a developmental disorder characterized by a highly sociable personality, has found a series of structural, functional and connectivity deficits that converge on a part of the brain called the insula. The findings were published online 12 March in Proceedings of the National Academy of Sciences.
