Some Ipsilateral Projections to Areas PF and PG of the Inferior Parietal Lobule in Monkeys.

摘要

Projections to the inferior parietal lobule were studied by retrograde axonal transport of horseradish peroxidase (HRP). Several cortical and subcortical areas projected to both areas PF and PG including the cingulate and periarcuate cortex, the basal nucleus of Meynert, several intralaminar nuclei of the thalamus, and the ventral lateral thalamic nucleus. However, area PF received afferents from the second somatosensory area of the parietal operculum, the oral pulvinar nucleus, and ventral parts of the medial pulvinar nucleus, whereas area PG received inputs from the banks of the superior temporal and occipitotemporal sulci and from the dorsal parts of the medial pulvinar and lateral posterior nuclei.
