According to the revised dopamine hypothesis of schizophrenia, which of the following statements correctly describes the relationship between dopamine activity, brain region, and schizophrenic symptoms?
Hyperdopaminergia in the subcortex (specifically the mesolimbic pathway) is linked to positive symptoms, whereas hypodopaminergia in the prefrontal cortex is linked to negative symptoms.
Hypodopaminergia in the subcortex (specifically the mesolimbic pathway) is linked to positive symptoms, whereas hyperdopaminergia in the prefrontal cortex is linked to negative symptoms.
Hyperdopaminergia is uniformly distributed across the entire cerebral cortex, causing positive symptoms, while hypodopaminergia is restricted to the spinal cord.
Hypodopaminergia in the temporal lobes is linked to positive symptoms, whereas hyperdopaminergia in the occipital lobes is linked to visual hallucinations.
