Worrying and anxiety are two big symptoms of—and causes of—depression. Worrying is mediated mainly by connections between several parts of the prefrontal cortex and the anterior cingulate. By comparison, anxiety is mediated by circuits within the limbic system. So there’s no reason to get upset with yourself for feeling anxious or worrying too much; it’s just a by-product of your brain’s evolution. Fortunately, understanding the brain circuits involved in worrying and anxiety can give you a better handle on the situation.
