The reticular formation has not been implicated in OCD. However, the other three areas mentioned (orbital region of the frontal cortex, caudate nucleus, and thalamus) have all been implicated in OCD. Dysfunction in the orbital frontal cortex may result in difficulty inhibiting inappropriate responses or behaviors, while abnormalities in the basal ganglia circuitry (which includes the caudate nucleus) may lead to the repetitive thoughts and compulsive behaviors characteristic of OCD. The thalamus may also play a role in OCD symptoms by over-reacting to anxiety-provoking stimuli.
