title: Extensive co-localization of neurotensin with dopamine in rat meso-cortico-frontal dopaminergic neurons.
abstract: In mammalian brain, dopaminergic (DA) cell bodies located in the ventral mesencephalon give rise to meso-cortical, meso-limbic and meso-striatal systems. Among these, the meso-cortical DA pathway is particularly involved in the processing of emotional and cognitive responses. We demonstrate that the rat meso-cortical neurons specifically contain, in addition to DA, another transmitter, Neurotensin. If this co-localization exists in man, it may provide an anatomical substratum for the biological theory of schizophrenia as well as an indication that potential anti-psychotic drugs which act differentially on the DA ascending transmissions can be developed.
