Abstract:
The thalamic connectivity and basal forebrain cholinergic input to the posterior parietal cortex (PPC) of Long-Evans rats was examined using combined retrograde tracing and immunocytochemical methods. As in previous studies, the PPC could be distinguished by its input from the lateral posterior, lateral dorsal, and posterior nuclei of the thalamus, but not the lateral geniculate nucleus or ventrobasal complex. These nuclei were also observed to receive reciprocal projections from the ipsilateral PPC. Cholinergic neurons innervating the PPC were primarily localized to the substantia innominata/nucleus basalis region. The implications of these data for possible functions of the cholinergic input to PPC are discussed.
