Figure 2. Effects of hemicerebellectomy on spinal cord.

M responses, H-reflex and F responses in control rats (A, top panels) and in hemicerebellectomized rats 48 h after surgery (B, bottom panels), before and after repetitive stimulation of the left sciatic nerve. Recordings in left plantaris muscle resulting from stimulation of the left tibial nerve. Left panels, M responses and H-reflexes at time 0 (basal state, filled circles) and time +60 min (open circles). Mean values ±s.d. are shown. Persistence and mean F/mean M wave ratios are illustrated in right panels (means ±s.d.; filled bar, time 0; open bar, +60 min). Values are means ±s.d.*P < 0.05.
