CORTICAL LOCALIZATION OF TASTE IN ALBINO RAT

Abstract

The cortical receptive zones for the IXth and chorda tympani nerves in the rat were located by the evoked potential method using electrical stimulation applied directly to the nerves. Bilateral ablations of this region produced permanent increases in quinine hydrochloride thresholds as measured by the two-bottle preference method. Destruction of any other part of the neo-cortex produced no threshold changes.
