This pathway is thought to be associated with the negative symptoms of schizophrenia, which include avolition, alogia and flat affect (lack of emotional response).
receptors in the dopaminepathways in the brain, so the normal effect of dopamine release in the relevant synapses is reduced.
receptors in the mesolimbic pathway of the brain which is thought to produce the intended antipsychotic effect.
Typical antipsychotics are not particularly selective and also block the same receptors in the mesocorticalpathway, tuberoinfundibular pathway and the nigrostriatal pathway.
