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., associate professor of neurological surgery, neurology, and psychiatry, and Genevieve Konopka, Ph.D., associate professor of neuroscience, the genetic basis of this process is not clear.
