The response magnitude of cells in the infragranular layer of the hindlimb cortex correlated with % weight supported steps in exercised spinalized rats. A. Photographs of two adult rats with neonatal T8/T9 transections performing treadmill exercise (a mirror is placed behind the treadmill to ensure all activity of the hindlimbs is captured). On the left is one exercised spinalized rat exhibiting no weight support. The hindquarters are dragged on the surface of the treadmill. On the right is an exercised spinalized rat exhibiting a weight supported step. The hindlimbs are supporting the hindquarters above the surface of the treadmill. B. The average weight supported steps for 8 rats were obtained after electrode implantation in the hindlimb somatosensory cortex. Each box represents different days of the sensory maps. Five rats had undergone two different days of sensory maps, while three rats had one sensory map. The average response magnitude of the cells were positively correlated with %WSS (**p<0.01).
