Question

Quizplus · Accepted Answer

The basal ganglia has been implicated in both obsessive-compulsive disorder and attention deficit/hyperactivity disorder. Dysfunction in the basal ganglia can lead to abnormalities in motor control and inhibition as well as cognitive and emotional processing, which are all relevant to these disorders. The cerebellum is involved in motor control but has not been linked to these disorders. The thalamus is involved in sensory processing and regulation of consciousness but is not directly implicated in these disorders. The red nucleus is primarily involved in motor control and has not been linked to these disorders.
