Document Summary
What is neurotransmission: neurotransmission: process by which neurons communicate, communicate at the junction of the axon terminal and soma (cell body) or dendrite, synaptic transmission has two major components, electrical signaling via action potentials, chemical signaling via neurotransmitters. Tend to hit a bunch of dopamine receptors, not just the one: d2 is usually inhibitory, so the positive symptoms will be blocked. Can basically zone people out: negative symptoms are harder to treat (increase mesocortical. D1 activity: possible treatments could include reuptake inhibitors. Ssris: depolarization along the axon, attaches to dendrites or cell body, and creates synaptic cleft at junction. Classifying neurotransmitters: classification by function, excitatory, ex: glutamate excites taste buds, inhibitory, ex: gaba, classification by structure, small-molecule, ex: gaba, classification by structure, small-molecule, ex: dopamine, neuropeptides, ex: oxytocin, gaseous transmitters, ex: nitric oxide. The structures of neurotransmitters: adrenaline, noradrenaline, dopamine, serotonin, gaba, acetylcholine, glutamate, endorphins.
