Supplementary Figure 2: Both narrow and wide units can respond to passive movement and imagined gait.

Pie charts depict numbers of wide and narrow units for which the firing rate either increased (black), decreased (white) or showed no change (grey). In total, 76 narrow, and 10 wide-spike neurons were tested during passive limb movement. For narrow-spike units, 13 (17%) responded with an increase in discharge while 36 (47%) were inhibited. For wide-spike units, only 1 (10 %) responded with increase in discharge while 4 (40%) showed a decrease in discharge. During imagined gait we tested 80 narrow-spike units and 14 wide-spike units. For narrow-spike units 14 (18%) responded with an increase in firing rate, while 44 (55%) had a decrease in firing during imagined gait. For wide-spike neurons 2/14 (14%) increased their discharge during imagined gait and 7/14 (50%) were inhibited during imagined gait.
