LINCOLN, Neb. (AP) — Understanding how concussions affect the brain is a hot topic in sports and medicine, so an expert from the University of Nebraska-Lincoln will explain some of the latest research later this month.

Dennis Molfese is director of UNL’s Center for Brain, Biology and Behavior. He will give a talk on Oct. 23 about how concussions can sometimes have lifelong effects.

Molfese will also describe what’s being done to understand concussions better in the 12:15 p.m. talk at Memorial Stadium’s West Stadium Club.

Molfese is part of a national committee studying sports-related head injuries. He was also part of a National Academy of Sciences committee that looked at concussions in youth sports.
