Figure 2: Distribution of AMPAR plasma concentrations in A: (1) all enrolled athletes (n=84) and (2) not recovered from prior concussion athletes (n=7). Dynamic changes of plasma AMPAR peptide for three subjects (B); Distribution of NR2 plasma concentrations in C: (1) all enrolled athletes (n=84), (2) subjects returned for longitudal study (n=18). Dynamic changes of plasma NR2 peptide for three subjects (D). Dotted lines show corresponding cut offs: 0.4 ng/mL for AMPAR peptide and 0.5 ng/mL for NR2 peptide. |
