Figure 6. Changes in firing probability of an EDC MU after stimulation of the homonymous and heteronymous group I afferents.

Figure 6

PSTHs of an EDC MU are compared after stimulation of the homonymous Ia afferents in the radial nerve in the spiral groove (0.9MT; A–B) and of the ulnar nerve at wrist level at 1MT (C–D). Abscissa and ordinate, and open, filled and hatched columns as in Fig. 1. Bin width 0.5 ms. The heteronymous peak was significant (P < 0.01). The difference between the latencies of the homonymous (B, 28.5 ms) and heteronymous (D, 33.5 ms) peaks was 5 ms. Distance between wrist and elbow electrodes, 33.5 cm.
