A modality-specific somatosensory area within the insula of the rhesus monkey

Brain Res. 1993 Sep 3;621(1):116-20. doi: 10.1016/0006-8993(93)90305-7.


Response properties of neurons in the monkey's granular insula (Ig) were examined with somatic, auditory, visual, and gustatory stimuli. Results indicate that a major portion of Ig is a somatic processing area exclusively, with units that have large and often bilateral receptive fields, consistent with the view that this area serves as a higher-order, modality-specific link in the somatosensory-limbic pathway.
