Somatosensory cortical map changes following digit amputation in adult monkeys
Michael M. Merzenich,R. J. Nelson,Michael P. Stryker,Max S. Cynader,Axel Schoppmann,John M. Zook +5 more
TL;DR: The cortical representations of the hand in area 3b in adult owl monkeys were defined with use of microelectrode mapping techniques 2–8 months after surgical amputation of digit 3, or of both digits 2 and 3.
Journal ArticleDOI
Topographic reorganization of somatosensory cortical areas 3b and 1 in adult monkeys following restricted deafferentation
TL;DR: This paper found that after the median nerve was transected and ligated in adult owl and squirrel monkeys, the cortical sectors representing it within skin surface representations in Areas 3b and 1 were completely occupied by 'new' and expanded representations of surrounding skin fields.
Journal ArticleDOI
PROGRESSION OF CHANGE FOLLOWING MEDIAN NERVE SECTION IN THE CORTICAL REPRESENTATION OF THE HAND IN AREAS 3b AND 1 IN ADULT OWL AND SQUIRREL MONKEYS
TL;DR: The results of studies directed toward determining the time course and likely mechanisms underlying this remarkable plasticity of the cortex representing the skin of the median nerve within parietal somatosensory fields 3b and 1 are described.
Journal ArticleDOI
Multiple representations of the body within the primary somatosensory cortex of primates.
TL;DR: In this article, the classical primary somatosensory cortex of monkeys consists of as many as four separate body representations rather than just one, and two complete body surface representations occupy cortical fields 3b and 1.
Journal ArticleDOI
Representations of the body surface in postcentral parietal cortex of Macaca fascicularis
TL;DR: The somatotopic organization of the postcentral parietal cortex of the Old World monkey, Macaca fascicularis, was determined with multi‐unit microelectrode recordings and it is suggested that the representation in Area 3b is homologous to “SmI” (or “SI”) in non‐primates.
