Afferent connections of medial precentral cortex in the rat

The principal sources of input to rat medial precentral cortex (PCm), as revealed by iontophoretically applied horseradish peroxidase, are: the ventral lateral, mediodorsal, central lateral and ventromedial thalamic nuclei; contralateral PCm; ipsilateral cortical areas related to vision, somatic sensation and audition; retrosplenial and ventrolateral orbital cortex. These results are compared to findings in monkeys and discussed in relation to the phenomenon of polymodal neglect of hemispace.
