Decoding memory-forming brain cell conversationsThe conversations neurons have as they form and recall memories have been decoded by Medical College of Georgia scientists.
The breakthrough in recognizing in real time the formation and recollection of a memory opens the door to objective, thorough memory studies and eventually better therapies, said Dr. Joe Tsien, neuroscientist and co-director of MCG's Brain & Behavior Discovery Institute.
