(a)–(f) The grand average summary of the effects of CCI on major SSEP peaks. As in Fig. 4, red data points indicate postinjury averages over all animals $(n=10)\pm \mathrm{SD}$ and are normalized to baseline values (blue data points). The time of impact is designated here as $t=0\mathrm{s}$, and significance relative to baseline is indicated by asterisks, as in Fig. 4. (g) A montage of SSEP waveforms taken repeatedly over the course of an hour in a sham experiment.
