  • His research also demonstrated that antipsychotic medications, used primarily in the treatment of schizophrenia, affect the transmission of signals via dopamine by blocking dopamine receptors. (lu.se)
  • This dramatic increase coincides with the introduction of a range of new neurochemical and pharmacological tools for the study of dopamine neurons and their function in the brain, as well as the identification of the dopamine receptors, their pharmacology, and their role in mediating the antipsychotic action of neuroleptics [12,13].
