Can We Turn Down The Emotion On Traumatic Memories?

A small structure in the brain could hold the keys to future therapeutic techniques for treating depression, anxiety, and PTSD, someday allowing clinicians to enhance positive memories or suppress negative ones, according to Steve Ramirez, an assistant professor of psychological and brain sciences at Boston University. Inside our brains, a cashew-shaped structure called the hippocampus […]

Neurons That Suppress Fear Memories Hide In The Hippocampus

A group of cells in the brain that are responsible when a frightening memory re-emerges unexpectedly has been found by neuroscientists at the University of Texas at Austin. The discovery could lead to new recommendations about when and how often certain therapies are deployed for the treatment of anxiety, phobias and post-traumatic stress disorder (PTSD). […]

Dopamine Neuron Activity Is Key To Conditioned Fear Extinction

When a feared outcome does not happen, activity in midbrain dopaminergic neurons is required to get rid of behavioral fear responses, researchers at the RIKEN Center for Brain Science have found. Their study study details the role of dopamine in ensuring that rats lose fear response in the prolonged absence of the stimulus. Like animals, […]
