A controversial new approach that quiets the activity of certain neurons in the brain alleviates breathing difficulties in a mouse model of Rett syndrome, according to a study published 4 October in the Proceedings of the National Academy of Sciences.
Researchers have developed the first stem cell system that makes it possible to study the early development of neurons from people with Rett syndrome, a rare disorder on the autism spectrum.
Researchers are exploring the iPad and other touch-screen devices for their potential to help people with autism communicate more effectively. Until studies prove their efficacy, however, some experts hesitate to recommend their use.
The amygdala, a brain region that regulates fear and anxiety, shows abnormal neuronal signaling in a mouse model of fragile X syndrome, according to two studies published this summer. These are the first to explore cellular defects in the region in fragile X.
Researchers have uncovered an important molecular piece of a learning mechanism that occurs at the junction between neurons. The findings, which may help understand how the brain is disrupted in disorders such as autism, appear in the 24 June issue of Neuron.
