Photobiomodulation (PBM) ameliorates cognitive deficits in AD mice. A Experimental timeline showing 808 nm light treatment and behavioural tests. B Representative swimming track of mice in Morris water maze (MWM) test. C Bar graphs of latency to find the escape platform, platform crossing number, and time in target quadrant in the test session of MWM. D Representative movement tracks in open field test (OFT). E Bar graphs of level score and time in centre of the OFT. Experimental data are presented as the mean ± standard deviation, n = 6 mice per group. Compared with the CON group, **p < 0.01, ***p < 0.001; Compared with the AD group, #p < 0.05, ###p < 0.001
