Document Summary

1: release neurotransmitters from vesicles with or without an action potential, block reuptake or block receptors, prevent vesicles from releasing the neurotransmitter. Inhibits the effects of glutamate in the cerebellum (balance) Prevents dopamine from breaking down in the nucleus accumbens, which is in basal ganglia. Alcohol binds to gaba receptors causing the cell to hyperpolarize (not fire) Decreased activity in the prefrontal cortex (judgment) and hippocampus (memory) Increases dopamine levels which are used for reward and motivation say drinking is rewarding which in turn makes you want to do it again. Thc encourages cannabinoid receptors to mimic other neurotransmitters in the limbic system, cerebellum and basal ganglia: decreases acetylcholine in hippocampus, decreasing action of other neurotransmitters in those areas. Trade name for flunitrazepam (aka date rape drug or roofies . Depress the central nervous system by binding to gaba receptors: this increases the chance gaba binds to the receptor, gaba is an inhibitory signal.
