Drexel Researchers Explore the Anatomy of Recollection in Epilepsy Patients

What was your high school mascot? Where did you put your keys last night? Who was the first U.S. president? Groups of neurons in your brain currently are sending electromagnetic rhythms through established pathways in order for you to recall the answers to each of these questions. And now researchers at the Drexel University School of Biomedical Engineering, Science and Health Systems are getting a rare look inside the brain to discover the exact pattern of activity that produces a memory.

“When performing seizure mapping, surgeons implant electrodes in many brain areas, while searching for seizure activity,” says Joshua Jacobs, PhD, of Drexel, who is analyzing data accumulated from 60 epilepsy patients who have had electrodes implanted on their brains in order to determine the causes of their epileptic episodes. “Thus, there many electrodes end up being in normal brain tissue, and they measure neuronal activity that reflects normal brain function — this is the function that we’re studying to learn about the nature of working memory.” For more information, click here to read the full release.
