All 11 line scans from pre- to postinjury in a single SCI experiment. The time scale for scanning indicates the progression of the SCI, the bleaching process, and the position of the scan, because of the simultaneous bleaching that is occurring. Note that this is an “injury” experiment and “control” experiments were performed in exactly the same manner, including total time intervals, except no impaction/injury was performed. The preinjury scan is in the back with the successive scans in front. This is plotted so that the earliest scan is displayed translated slightly to the right and the later scans extend slightly to the left. Semi-log plots of IE for all scans at any particular Raman shift are essentially linear over the initial 5 h post-SCI including the preinjury scan.
