We studied the effects of peripheral and central administration of SCH 23390, a selective antagonist of dopamine D1 receptors, on intracranial self-stimulation of the medial prefrontal cortex of the rat. Intraperitoneal injections of SCH 23390 produced a dose-related decrease in self-stimulation. Unilateral microinjections of SCH 23390 into the medial prefrontal cortex also produced a dose-related decrease in self-stimulation in the ipsilateral medial prefrontal cortex. However, self-stimulation of the contralateral, noninjected prefrontal cortex, used as control, was not affected. Together with previous data, the present results suggest that the dopamine neurotransmission involved in self-stimulation of the prefrontal cortex of the rat is mediated by dopamine D1 receptors.

D001552 Benzazepines Compounds with BENZENE fused to AZEPINES.
D012653 Self Stimulation The act or process of inducing or increasing the level of arousal in oneself. It can be observed in various situations; for example, infants who are understimulated may explore their surroundings or babble to themselves.(https://dictionary.apa.org/self-stimulation accessed 12/30/2020) ICSS Intracranial Self-Stimulation,Intracranial Self Stimulation,Self-Stimulation,Intracranial Self Stimulations,Self Stimulation, Intracranial,Self Stimulations,Self Stimulations, Intracranial,Self-Stimulations,Stimulation, Self,Stimulations, Self

D017397 Prefrontal Cortex The rostral part of the frontal lobe, bounded by the inferior precentral fissure in humans, which receives projection fibers from the MEDIODORSAL NUCLEUS OF THE THALAMUS. The prefrontal cortex receives afferent fibers from numerous structures of the DIENCEPHALON; MESENCEPHALON; and LIMBIC SYSTEM as well as cortical afferents of visual, auditory, and somatic origin.
