Rhesus Monkey Vestibular Cortex: A Bimodal Primary Projection Field

Abstract

Single units in the rhesus monkey (Macaca mulata) cortex responded to both vestibular and proprioceptive somatosensory stimuli. This bimodal response characteristic is unlike the modality specificity noted for other primary sensory fields. The vestibular field is located, contrary to previous opinion, within a distinct cytoarchitectonic area outside of area 2.
