Scientists have made a recent breakthrough concerning how anxiety is regulated in the vertebrate brain. Their work may show how the brain normally shuts off anxiety, that is, by disrupting a specific set of neurons in the habenula brain region, which prevents normal response to stressful situations.

The results of a small clinical trial suggest that targeting the brain's anterior capsule with precise, high-intensity radiation led to dramatic improvements in people with severe obsessive-compulsive disorder (OCD). (Neurosurgery, 2011; 68: 28–33) Read more. [163]
Researchers have found that one exposure to acute stress affects information processing in the cerebellum, the area of the brain responsible for motor control and movement coordination and is involved in learning and memory formation. The results lead to a testable prediction that emotional stress could affect motor coordination and other cognitive functions, and may also prove to be applicable to the alleviation of PTSD, drug addiction, and other disorders.
