Document Summary
Act on neurons in immediate vicinity: neuromodulators. What are the different classes of neurotransmitters: small molecules. Peripheral nervous system: autonomic: both pre-ganglionic, parasympathetic post- ganglionic, somatic: neuromuscular junction. Central nervous system: projections from basal forebrain to hippocampus and amygdala; septal area; brainstem. Behaviors: autonomic function, movement, learning and memory. Synthesis: choline + acetate via enzyme choline acetyltransferase (chat) Mediates inhibition and excitation in target cells. Degradation: reuptake or broken down by acetylcholinesterase (ache) Ventral tegmental area hippocampus, amygdala, nucleus accumbens, and frontal lobe. D1, d5 = stimulatory g-protein coupled receptors. D2, d3 and d4 = inhibitory g-protein coupled receptors: norepinephrine. Widespread projections from locus coeruleus (pons); medulla; hypothalamus. Widespread projection from raphe nucleus to brain and spinal cord. Sleep/wake cycle, appetite, mood, aggression and social rank. Psych 3313: at least 15 types and subtypes, most are metabotropic; excitatory or inhibitory, melatonin. Histamines: projections originate from basal posterior hypothalamus, mast cells, associated with wakefulness. Gaba: principle inhibitory neurotransmitter, mood, receptors.
