Answer 27

• emotional response center
• sham rage, aggressive behavior
• projects to cingulate gyrus
• projects to same cortial area as the lateral dorsal nucleusjj

Question 28

suprachiasmatic nucleus

Answer 28

• helps regulate circadian rhythms
• lesion would lead to difficulty sleeping; take melatonin
• receices input from the dentate nucleus of the cerebellum
• receives input from both basal ganglia and cerebellum
