(FRAME-INFO (STRING "Somatosensory Homunculus. \(Image redrawn and modified from W. Penfield & T. Rasmussen, The Cerebral Cortex of Man. Macmillan Publishing, 1950\). Representative maps such as this one, showing where regions of the body are represented in the cerebral cortex, are derived from electrical stimulation studies in both animals and humans.  Note the greater amounts of cortex devoted to the fingers and lips as compared with the trunk and foot. In general, regions of the body with higher densities of receptors have larger representations in the cortex. The projection \(somatosensory radiation\) from the thalamus to the cortex is shown by arrows; VPM and VPL stand, respectively, for ventral posterior medial and ventral posterior lateral thalamic nuclei.
