Extinguishing fear memories relies on an unusual change to DNA


Researchers have discovered a DNA modification that enhances our ability to extinguish fear. The findings could help guide the development of new treatments for fear-related anxiety disorders. Professor Timothy Bredy of UQ’s Queensland Brain Institute (QBI) said while fear is an important survival mechanism which uses cues in the environment to prompt certain responses, so too is the ability to inhibit fear when it’s no longer needed.
