Between Group Comparisons of GFAP at the Sulcal Depth. At the depth of the sulcus, no significant differences in GFAP were detected at the subpial surface (A, D). Within the underlying cortical grey matter, the Blast-RHI, RHI), and RHI CTE) groups all had significantly higher mean fluorescent GFAP intensity compared to controls (E), with no differences detected in any groups for percent positivity (B). At the grey-white matter junction, all neurotrauma groups had significantly higher GFAP in terms of mean fluorescent intensity compared to controls (F). No differences were detected in percent positivity at the GWMI (C). Error bars represent standard error of the mean. *P < 0.05, **P < 0.01
