Which dopamine pathway is responsible for negative symptoms of schizophrenia?

The correct answer is D, the Mesocortical pathway. This pathway is responsible for regulating cognitive and emotional functions. Dysfunction in this pathway is associated with the negative symptoms of schizophrenia, such as cognitive deficits and emotional blunting. The Mesolimbic pathway (A) is linked to positive symptoms, Nigrostriatal pathway (B) to motor control, and Tuberoinfundibular pathway (C) to hormone regulation. Therefore, they are not responsible for negative symptoms of schizophrenia.
