| Research Abstract |
In this study, to identify the precise localization of dopamine receptor D5 (D5R) in the rat prefrontal cortex, we observed the D5R-immunolabeled structures by confocal laser microscopy. As a result, we found that nearly all neurons, both excitatory and inhibitory neurons, contained D5R, and that the intracellular distribution pattern of D5R is markedly different between them. These findings strongly suggested that the differential distribution pattern of D5R may underlie dopaminergic modulation of cognitive functions subserved by the prefrontal cortex.
