What lobe of the brain is more active in OCD?

In individuals with obsessive-compulsive disorder (OCD), the frontal lobe, particularly the orbitofrontal cortex, shows increased activity. This area is involved in decision-making, impulse control, and the processing of emotions and risk. Additionally, the basal ganglia and the anterior cingulate cortex are also implicated, contributing to the symptoms of obsessions and compulsions characteristic of OCD.
