Light-activated compound silences nerves, may one day help epileptics

A compound that halts nerve cell activity when exposed to light glows in this image of two nerve cells.Brain activity has been compared to a light bulb turning on in the head. Scientists at the School of Medicine have reversed this notion, creating a drug that stops brain activity when a light shines on it. The new compound activates the same receptor used by many anesthetics and tranquilizers, making it harder for a brain cell to respond to stimulation. The drug may some day be used to treat epilepsy.

Genes and genius: Researchers confirm association between gene and intelligence

If you’re particularly good with puzzles or chess, the reason may be in your genes. A team of scientists, led by psychiatric geneticists at the School of Medicine, has gathered the most extensive evidence to date that a gene that activates signaling pathways in the brain influences one kind of intelligence. They have confirmed a link between the gene, CHRM2, and performance IQ, which involves a person’s ability to organize things logically.
