Table 1 ICMS effects in the ipsilesional hemisphere. For each lesioned monkey, the total number of ICMS sites tested is given in the rightmost column, separately for the ICMS sessions pre- and post-lesion. These ICMS sites tested were then distributed in three groups, depending on whether no effect was observed ("non-microexcitable" sites) or elicited movements of the hand ("digit" sites) or movements of other body territories ("other territories"), such activation of wrist, elbow, shoulder or face muscles. Between parentheses, the number of ICMS sites in each group is given in %. For each line, the sum of the three groups is 100%.
