Neuroscientists from the Tokyo University of Sciences, who recently published a study in Behavioral Neuroscience, think they have found the answer for erasing, instead of facing, memories that switch on fear. This is known as fear extinction. Your brain synthesizes a compound known as KNT-127 that activates delta-opioid receptors which are associated with mood. While the scientists were aware it was behind fear extinction from a previous study, what exactly activates it had been a mystery until now.
