Somatotopic organization of the second somatosensory cortical area after lesions of the primary somatosensory area in infant and adult cats.
The somatotopic organization of the second somatosensory cortical area (SII) and receptive fields of multineuron responses to cutaneous stimulation were studied in cats 6-16 months after lesions of the forelimb representation in the primary somatosensory area (SI) at 4 days, 4 weeks of age or in adults. No change was detected in SII. The results contrast with findings of alterations in SII of macaque monkeys following similar ablations of SI.
