Scientists switch memory recall on and off in fruit flies
... to answer an age-old question in neurobiology: Is persistent electrical activity necessary for memory formation? "The surprising answer is no!" says Tully. "A simple form of memory can be acquired and stored normally in the absence of electrical activity, but recall is blocked. This suggests that these memori...Common genetic mutation linked to uterine cancer
