Spontaneous firing in the spinal dorsal horn. Example recorded voltages from neurons with (a) no baseline firing and (b) baseline firing greater than 1 spike/sec. (c) The number of quiescent neurons (presented as percent of total neurons) was unchanged at 6 hours relative to sham at that time point, but at 1 day was significantly lower (*p=0.038) after injury compared to sham. (d) The number of active neurons exhibited a similar trend with a significantly greater number of neurons (*p=0.006) at 1 day after injury. Percentages of cells in the normal group are shown (dotted line) for (c) and (d).
