Pearson r correlation analyses were performed between levels of αII-spectrin or SBDPs in CSF and brain tissues by region and time point post injury. Protein levels were determined by Western blot at each time point post injury and were expressed as normalized values for CSF markers and as a percent sham for tissue markers for analysis. Sham, Probe, and PBBI injured rats were all included for analysis. Significant correlations are marked with
(p < 0.05),
(p < 0.01),
(p < 0.001), or
(p ≤ 0.0001).
