Document Summary

What are the major structures of the brain. Synaptic transmission: explains the delay in response latency for a reflex arc. Neurotransmitters: acetylcholine, norepinephrine, dopamine, serotonin, gamma- aminobutyric acid, Drug effects: increase or decrease amount of transmitter, processes that terminate transmitter action, stimulates or blocks receptor sites. The effect of ecstasy mdma blocks the reuptake of serotonin: the research of it on. A single neuron can be synapse with many other: repeatedly firing one neuron, both squid increase the friendliness and the interaction of them. excitatory neurons can generate the action potential. Cancel each other out (math- like); constantly generate inhibitory hyperpolarize (below the resting potential) (might be stopped by firing the other excitatory or inhibiting the inhibitory one) 100 billion neurons; 100 thousand miles of axons: Old brain: thalamus (many other animals share this similar structure), midbrain (doing interesting things to keep us alive), pons, medulla.
