Research Identifies a Way to Block Memories Associated with PTSD or Drug Addiction (video) University of Western Ontario Share Print E-Mail Loading video... Caption New research from Western University could lead to better treatments for Post-Traumatic Stress Disorder (PTSD) and drug addiction by effectively blocking memories. Steven Laviolette and Nicole Lauzon describe how a common mechanism in a region of the brain called the pre-limbic cortex can suppress the recall of memories linked to both aversive, traumatic experiences associated with PTSD and rewarding memories linked to drug addiction, without permanently altering memories.
