  • Title: [Organization of motor representation in the neocortex of white rats: results of macro- and microstimulation].

    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1982; 32(1):122-9. PubMed ID: 7064554.
    Abstract:
    Motor and EMG responses were studied in thirty rats craniotomized under thiopental, in conditions of intracortical microstimulation and surface anode macrostimulation of the parietal and frontal neocortical areas. Strict contralaterality and distinct separation was found in motor representation (MRs) of the fore and hind limbs, of vibrissae fields and even of some joints and functional muscle groups. On the territory of the hind leg MR which was studied in greater details, centrally lies the compact MR zone of toes, mediocaudally from it - a vast MR of the foot, and further still more caudally and with some overlapping, the MRs of the shin, thigh and pelvic-abdominal musculature, respectively.
