Figure 4. Effect of 810-nm laser on mitochondrial membrane potential (MMP) in cortical neurons with excitotoxicity.

Figure 4

(A) TMRM (red) fluorescence for MMP and Hoechst (blue) fluorescence for nuclei in cortical neurons as control and with 3 excitotoxins, with and without LLLT (3 J/cm2 810 nm laser). Scale bar = 20 µm. (B) Quantification by Image J of mean fluorescence values. N= 6 fields per group. Error bars are SEM and * = p <0.05; ** = p<0.01 vs sham (dark).
