dopamine hypothesis - ANSWER the theory that schizophrenia results from excessive activity of the neurotransmitter dopamine What is the path of dopamine suppression by 5-HT? - ANSWER 5-HT2A antagonism by atypical antipsychotics decrease serotonin release, thereby stimulating downstream dopamine. Increased dopamine reduces glutamate which inhibits release of inhibitory GABA (inhibits dopamine) Mesolimbic dopamine hypothesis: Hyperactivity of dopamine neurons in the mesolimbic dopamine...
