Cognitive behavioural therapy is the best-studied form of psychotherapy. But researchers are still struggling to understand why it works (Single Link Nature.com).
People with depression tend to have detectable differences in two primary brain systems: the prefrontal cortex, which is responsible for complex mental tasks such as self-control and planning, and the limbic system — including the amygdala — which is involved in emotional processing. In healthy people, the prefrontal cortex can inhibit amygdala activity, keeping emotions in check. But imaging shows that in many people with depression, the prefrontal cortex seems to be less active. “Depressed people have what you might think of as a trigger-happy amygdala.”
