Unlearning Fear

Forget it! A biochemical pathway for blocking your worst fears? 03/25/09. A receptor for glutamate, the most prominent neurotransmitter in the brain, plays a key role in the process of "unlearning," report researchers at the Salk Institute for Biological Studies. Their findings, published in the current issue of the Journal of Neuroscience, could eventually help scientists develop new drug therapies to treat a variety of disorders, including phobias and anxiety disorders, particularly post-traumatic stress disorder.
