Fig. 3: The overall contextual fear is reduced by applying PBM after memory recall.
From: Photobiomodulation prevents PTSD-like memory impairments in rats
A The behavioral test paradigm for memory recall. B In female Res-group rats, a strengthened cued memory was observed at day 16 compared with No res-group (n = 8) ($P < 0.05, t-test, percentage of freezing to tone was shaded with gray as cued memory), which indicates a step towards the development of cued hypermnesia. Compared with Res-group (n = 10), female rats in PBM-group (n = 12) exhibited less freezing response during the contextual and cued memory test (**P < 0.01, two-way ANOVA with repeat measures). C In males (Res & PBM, n = 8 each), both contextual and cued memorries were intense, and PBM had no effects. The baseline is the percent of freezing before tone presentation in a novel context-B. D The context and tone conditioning ratio calculated at day 16 for both sexes. Data are mean ± S.E.M.
