Changing the Emotional Association of Memories

New research by HHMI scientists shows that the emotional memory of an experience is malleable.

By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories. The research, led by Howard Hughes Medical Institute investigator Susumu Tonegawa at the Massachusetts Institute of Technology (MIT), reveals that the connections between the part of the brain that stores contextual information about an experience and the part of the brain that stores the emotional memory of that experience are malleable.
