  2. What neurotransmitter does the locus coeruleus release, and what are its effects on behavior?
    • Norepinephrine
    • Effect: increases info storage during wakefulness, supresses REM sleep

    • Acetylcholine: excites thalamus and cortex; increases learning, attention; shifts sleep from NREM to REM
    • GABA: Inhibits thalamus and cortex
  4. What neurotransmitters does the hypothalamus release, and what are their effects on behavior?
    • Histamine: Increases arousal
    • Orexin: maintains wakefulness
