Document Summary

The neural impulse: all-or-none law: the action being made has to fully happen or not happen at all. The action cannot half-happen, just like you can"t half-fire a gun. However, you can change the rate at which the action happens. Inhibitory psp: negative voltage shift that decreases the likelihood that the postsynaptic neuron will fire action potentials. Integrating signals: neural networks: synaptic pruning: key process in the formation of the neural networks that are crucial to communication in the nervous system. Include three neurotransmitters: dopamine, norepinephrine, and serotonin: dopamine is used by neurons that control voluntary movements, serotonin controls the regulation of sleep and wakefulness and eating behaviour, gaba and glutamate (amino acid transmitters, gaba. Widely distributed in the brain responsible for the inhibition in the central nervous system contributes to anxiety in humans: glutamate. Always has excitatory effects contribution to learning and memory: endorphins.
