Adjacent to this pleasure centre, there is Pain centre that releases Endorphins for regulating the pain sensation. The secretion of Dopamine and Endorphins is related.

A criticism of biochemical explanations of schizophrenia is that they are reductionist i.e. they reduce a complex behaviour such as schizophrenia down to a relatively simple level of explanation i.e. an imbalance in brain chemicals. The influence of brain chemicals such as dopamine is indisputable but to argue that they can cause schizophrenia ...
