Document Summary

We know how some drugs influence the nervous system. Inhibits reuptake of serotonin (this increases the amount of serotonin in the synapse and this increases the activity of the postsynaptic neuron. Inhibit reuptake of dopamine and other neurotransmitters. Brain atrophies with many years of drinking. They can reach many target cells (including neurons) Some hormone receptors can be on the axon terminal. Can influence the amount of calcium" per say coming into the neuron. Some hormones (e. g testosterone, estrogen) bind to receptors inside neuron. Can change number of channels and/amount of neurotransmitter produced, etc. Can alter what proteins are being made. Hormones can influence human behaviour, but does not control it. Hormones produced by testes and adrenal glands. Important for maturation of secondary seual characteristics. Levels of testosterone in their blood levels correlate with their aggressiveness. Castrating male rats (source of testosterone) decreases their aggressiveness. Testosterone does not reliably correlate with aggression. Castrated males do not decrease in aggressiveness.
