BrdU-NeuN double-staining images and analyses at the neurogenic hippocampal DG at the 7 days point; (a) sham, (b) CCI-TBI, (c) $1\times$ tLLLT, (d) $3\times$ tLLLT, (e) mean BrdU/DAPI $\text{ratios}\pm \mathrm{SD}$ ($n=5$); normalization of the readings was done BrdU versus DAPI (labeling the nuclei). Scale bar $100\mu \mathrm{m}$. *** $p<0.001$ versus sham; ††, ††† $P<0.01$, 0.001 versus TBI.
