Spotless Mind? Fear Memories In Humans Weakened With Beta-blocker Propranolol

Dutch scientists have successfully reduced the fear response. They weakened fear memories in human volunteers by administering the beta-blocker propranolol. Interestingly, the fear response did not return over the course of time. Until recently, it was assumed that a fearful memory could not be deleted. However, researchers have now demonstrated that changes can indeed be effected in the emotional memory of human beings.
