RBFOX3 and brain injury: Since the loss of NeuN immunoreactivity may predict neuronal degeneration in the rodent hippocampus after various brain injuries [26], we quantified separately NeuN labeling in the suprapyramidal (inner) blade and infrapyramidal (outer) blade of the hippocampal DG [27] in coronal sections of the control, SCA, and HBO-treated animals (Figure 2D,E).
