Figure 5. — Changes of spontaneous cortical activity in spinalized rats. (A) Examples of 20 s spontaneous recordings of local field potentials and multiunit activity from the forepaw cortex (black) and the hindpaw cortex (gray) before (left) and immediately after (right) complete thoracic transection of the spinal cord in a representative animal. (B) Power spectrum of the multiunit activity corresponding to the recordings shown in “A.” Before spinal cord transection, the somatosensory cortex of this animal showed marked oscillations at delta frequencies (3 Hz), but the oscillation switched to slow-wave activity (0.5 Hz) after the spinal cord transection.
