TL;DR

The observed deficits of tongue usage were related to frontal cortical lesion placement and thereby support recent electrophysiological mapping studies of the rodent motor and somatosensory cortex.

Abstract

Previous work has demonstrated that forelimb-digital usage is disrupted in rats with frontal cortical lesions. The present experiment indicates that other motor functions, specifically tongue usage, are also influenced by the rodent cerebral cortex. The observed deficits of tongue usage were related to frontal cortical lesion placement and thereby support recent electrophysiological mapping studies of the rodent motor and somatosensory cortex. Bilateral frontal cortical lesions which were placed in two operative stages with interoperative testing did not spare tongue usage.

The extent and organization of motor (MsI) and somatosensory (SmI) cortex in the rat were investigated using intracortical stimulation with semi-microelectrodes and single- or multiple-unit recording techniques to find overlap was essentially complete for the hindlimb, but only partial for the forelimb.

Microelectrode recording, systematic mapping, and cytoarchitectural techniques were combined in the present study to determine fine details in the patterns of somatic sensory projections from mystacial vibrissae, and other body regions, to SmI of the rat.

Brain ResearchThe effects of cortical ablations on digital usage in the rat

The ability of rats to perform a discrete digital task after cortical lesions was studied and six out of 8 rats with bilateral, frontal cortex ablation demonstrated a large drop in performance levels which persisted througout the 3 month testing period.
