Genes exert their strongest influence on the brain in the first half of gestation — a key window for autism and other neurodevelopmental conditions.

The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help...

Study identifies the key genes in the brain involved in encoding memories UT Southwestern scientists have identified key genes involved in brain waves that are pivotal for encoding memories. The findings, published online this week in  Nature Neuroscience, could eventually be used to develop novel therapies for people with memory loss disorders such as Alzheimer’s disease and other forms of dementia. Making a memory involves groups of brain cells firing cooperatively at various frequencies, a phenomenon known as neural oscillations. However, explain study leaders Bradley C. Lega, M.D., a...
