7. Action Potential

8. How Neurons Communicate…
IPSP = Inhibitory Postsynaptic Potential
EPSP = Inhibitory Postsynaptic Potential

9. Important for sleep, mood, learning; HIGH = Schizophrenia; LOW = Parkinson’s High Runner’s high INCREASED DOPAMINE
Aggression; Serial killers low levels; important for sleep and low levels assoc with depression
Runner’s High = DECREASED GABA
