DID PTSD: Researchers Identify Where Emotional Fear Memory And Pain Become Permanently Etched In The Brain

Researchers Identify Where Emotional Fear Memory And Pain Become Permanently Etched In The Brain: "Zhuo says that fear memory does not occur immediately after a painful event; rather, it takes time for the memory to become part of our consciousness. The initial event activates NMDA receptors -- molecules on cells that receive messages and then produce specific physiological effect in the cell -- which are normally quiet but triggered when the brain receives a shock. Over time, the receptors leave their imprint on brain cells."
