However, they have shown that oxytocin may modulate the activity in the mesolimbic dopaminergic pathway, as already discussed above, but in the case of schizophrenia, oxytocin may decrease the activity, supported by the fact that oxytocin has the capacity to inhibit the hyperactivity in the nucleus accumbens induced by drugs such as cocaine, methamphetamine, and phencyclidine [175]. The gene discussed is OXT; the disease is schizophrenia.
