The Brain and Behavior
Neurons are cells that are the building blocks of our major communication system, the nervous system.
They are comprised of a variety of parts
Neurotransmitters are chemicals that are excreted from the axon terminal and cross the synaptic cleft to the receptor sites on the dendrites.
Excitatory and inhibitory post synaptic potentials, all add up and see if the threshold for firing is determined on the subsequent Axon.
Dopamine influences movement, learning, attention, and emotions. Excess activity at dopamine receptors has been linked to schizophrenia.
Serotonin affects mood, hunger, sleep and arousal. Prozac raises serotonin levels (SRI).
Norepinephrine helps control alertness and arousal.
