Block and activate
Agonist = activator Antagonist = blocker
Dopa hypothesis
Dopamine might enlarge salience, and use of antipsychotic drugs has to do with dopamine. Has severe side effects ( parkinsonism). Limitations:
Only on positive symptoms, not in all patients, does not explaiin efficacy of other meds, simplistic view, dopamine is all around cortex
Glutamate hypothesis
NMDA receptor antagonism for negative and postive symptoms eg ketamine
NMDA is off in schizo, keta targets -, + and cognitive symtpoms
