Stimulation‐Induced Release of Coexistent Transmitters in the Prefrontal Cortex: An In Vivo Microdialysis Study of Dopamine and Neurotensin Release

Abstract: Extracellular fluid levels of dopamine and neurotensin in the rat prefrontal cortex were measured using in vivo microdialysis. Electrical stimulation of the median forebrain bundle resulted in increased release of both dopamine and neurotensin from the prefrontal cortex. Thus, stimulation of neurons in which dopamine and neurotensin are colocalized can evoke the in vivo release of both substances.
