particularly in the Nucleus Accumbens?
A. GABA
B. Dopamine
C. Acetylcholine
D. Serotonin

sleep (3 hours), and grandiosity. What is the most likely diagnosis?
A. Bipolar II Disorder
B. Cyclothymic Disorder

B. 3 months
C. 1 month
D. 1 year
Answer: A
Conceptual Explanation: Schizophrenia requires continuous signs of the disturbance for
