Control of Fear in the Brain Decoded: Emotional Balance Is Regulated by Molecular Factors Behind Stress Response, Max Planck Institute of Psychiatry Study

When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety. With the help of genetic studies on mice, scientists from the Max Planck Institute of Psychiatry have discovered two opposing neuronal regulatory circuits for the generation and elimination of fear. Both are controlled by the stress-inducing messenger substance corticotropin-releasing hormone (CRH) and its type 1 receptor (CRHR1).
