What are the three major hypotheses of psychosis and
their neurotransmitter networks? - Answer-Dopamine
theory - hyperactive dopamine at D2 receptors in the
mesolimbic pathway
, 3|Page
Glutamate theory - NMDA receptor hypofunction
Serotonin theory - 5HT2A receptor hyperfunction in the
cortex
Briefly explain the dopamine hypothesis of the positive
and negative symptoms of schizophrenia. - Answer-The
dopamine hypothesis of schizophrenia consists of:
There is too much dopamine activity in the mesolimbic
dopamine pathway, which leads to positive symptoms
(such as hallucinations and delusions).
There is also too little dopamine activity in the
mesocortical dopamine pathway, which leads to negative
symptoms (such as blunting of affect, poverty of speech,
anhedonia, and so on).
What pathway is responsible for regulating dopamine in
the hypothalamus and affects the release of prolactin? -
Answer-Tuberoinfundibular pathway
Drug-induced Parkinson's is caused by a decrease of
dopamine in what pathway? - Answer-Nigrostriatal
pathway
