Depression and Anxiety
In psychological tasks, such as self-evaluation, the frontal lobe provides regulatory control over emotional responses in limbic regions. Ongoing research in the EGI's Brain Electrophysiology Laboratory examines the dynamic changes in frontolimbic activity that discriminates clinically depressed and anxious from normal persons. By understanding these processes, we may be able to guide both biological and cognitive treatments for depression and anxiety.
