<p>Mean (n = 8–14) NSS scores measured over 4 weeks of mice in 9 groups consisting of sham TBI mice, sham control mice, 810-nm laser treated TBI mice (18 J/cm<sup>2</sup> delivered at 25 mW/cm<sup>2</sup>). (A) Mice and controls given 1 laser Tx or 1 sham Tx at 4 hours post TBI; (B) Mice and controls given 3 daily laser Tx or 3 sham Tx; (C) Mice and controls given 14 daily laser Tx or 14 sham Tx. * p<0.05; ** P<0.01; *** p<0.001. One way ANOVA. (D) Mean areas under curve of NSS time courses from mice in different groups. P values given were determined by one way ANOVA.</p
