Researchers are using this powerful tool to better understand how the brain reconstitutes consciousness and cognition after disruptions caused by sleep, medical procedures requiring anesthesia, and neurological dysfunctions such as coma. In a new study published in the journal eLife, a team led by anesthesiologists George Mashour, M.D., Ph.D. of Uni...

Syndicated Columnist Throughout the history of Davis & Elkins College, there have been a handful of individuals whose transformational leadership and commitment have fundamentally altered the trajectory of this institution. St. Louis resident Mr. James S. McDonnell III deserves an honored place on this elite list. Mr. McDonnell’s journey with Davis & Elkins College began when his daughter, Marcella McDonnell Stevens, enrolled at D&E in 1981. Four years later, at her graduation, Jim provided the commencement address. At that ceremony, he was awarded an Honorary Doctor of Laws. Jim and Eliza...

Your Feelings About Memories Shape Your Decisions People base their decisions on subjective memory—how they feel about a memory—more than on its accuracy, researchers report.   When we recall a memory, we retrieve specific details about it: where, when, with whom. But we often also experience a vivid feeling of remembering the event, sometimes almost reliving it. Memory researchers...

People base their decisions on subjective memory—how they feel about a memory—more than on its accuracy, researchers report. When we recall a memory, we retrieve specific details about it: where, when, with whom. But we often also experience a vivid feeling of remembering the event, sometimes almost reliving it. Memory researchers call these processes objective and subjective memory, respectively. The new study shows that objective and subjective memory can function independently and involve different parts of the brain. “The study distinguishes between how well we remember and how well...

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...
