Partial ablations of specific parts of cortical areas 3b (SI proper) and 3a in marmosets were found to render somatotopically equivalent parts of two other cortical somatosensory fields, the second somatosensory area (SII) and the parietal ventral area (PV), unresponsive to peripheral stimulation. Microelectrode recordings in anesthetized marmosets first established the responsiveness and locations of the representations of body parts, including the hand in areas 3a and 3b, SII, and in some cases PV. The hand representations in areas 3a and 3b were then removed by aspiration. Immediately afterwards, additional recordings established that regions of SII and PV that formerly represented the hand were no longer responsive to cutaneous stimulation of the hand (or any other skin surface). Other parts of these fields, representing parts of the body other than the hand, remained responsive to stimulation of the previously effective receptive fields. We conclude that SII and PV depend on inputs (either direct or indirect) from areas 3a and 3b for their activation.
