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

Abstract

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.

    Micro-electrode recordings from neurons in areas 7a and 7b in the macaque, homologues to the supramarginal gyrus in humans, and other TP regions have also shown activity in response to multi-sensory stimuli including proprioceptive stimulation [18–20]. Similar evidence also exists for neurons in the granular division of the insula [21]. Furthermore, lesion studies using Voxel-based Lesion Symptom Mapping (VLSM) and statistical Region Of Interest (sROI) mapping and diffusion tractography in stroke participants, have been used to study proprioceptive neuroanatomy, using robot-based assessments (Arm Position Matching (APM) and Kinesthesia (KIN) tasks) and passive movement of the upper limb [22–28].

    Moreover, both anatomical and resting-state functional studies found that the insula is interconnected to the temporal cortex (Flynn, 1999; Cauda et al., 2011). The somatosensory inputs may through the projection to the insula from temporal cortex reach insula and then the insula sends projection to amygdala (Schneider et al., 1993). From this perspective, the functional connectivity between temporal cortex and post insula in the present study may indicate the flow of emotional information processing.
