Frodl-Bauch, Thomas; Bottlender, Ronald; Hegerl, Ulrich (1999): Neurochemical substrates and neuroanatomical generators of the event-related P300. In: Neuropsychobiology, No. 2: pp. 86-94




The present review focuses on the current knowledge of the neurochemical processes and neuronal structures involved in the generation of P300. The increasing knowledge in this area facilitates the physiological interpretation of P300 findings as well as the link between P300 research and other research findings in biological psychiatry. Concerning the question of neurochemical substrates, the glutamatergic, GABAergic, cholinergic, noradrenergic, dopaminergic and serotonergic influences on P300 are reviewed. The knowledge of the generating structures of P300 is summarized from intracranial studies, magnetoencephalographic investigations, lesion and animal studies.
