“Metyrapone is a drug that significantly decreases the levels of cortisol, a stress hormone that is involved in memory recall,” explained lead author Marie-France Marin, a doctoral student.
Manipulating cortisol close to the time of forming new memories can decrease the negative emotions that may be associated with them, the researchers said.
“The results show that when we decrease stress hormone levels at the time of recall of a negative event, we can impair the memory for this negative event with a long-lasting effect,” said Sonia Lupien, Ph.D., who directed the research.
