Experts from the University of Illinois have found a link between the structure of the human brain and its propensity to anxiety. Orbitofrontal cortex is responsible for many functions, including anxiety. This zone forms a connection between the emotional and logical information, says Zee News.
Scientists tried to find the answer to the question: how to reduce anxiety in humans. It turned out, the thickening zone orbitofrontal cortex provides optimism and protects from excessive agitation, and anxiety.
Note, the rest of the structure had no effect on the person's attitude to various exciting factors. In the future, scientists plan to find out whether it is possible somehow to increase the level of optimism in humans, using knowledge about the structure and working of the brain.
