Figure 1. Spontaneous spinal activity with intact and lesioned spinal cord recorded in different spinal segments from the anesthetized cat.

A. Recordings of the initial conditions which showed synchronization and high correlation in different lumbar segments of CDPs. These are repeated throughout the recording at different time intervals as shown in traces. B. Spontaneous CDP recording made 75 minutes after deafferentation and a left spinal lesion between segments L5 and L6 at left side. It is showed a reduction in the synchronization of spontaneous CDPs. C. Right spinal lesion made 40 minutes after the left spinal lesion. The synchronization was almost abolished after the second spinal lesion between L5 and L6 at left side. See text for details.
