Effects of L-Cysteine administration on learning and memory deficits 28 days after HI. (A) Animal performance during the acquisition trial consisting of 4 trials per day for 5 days. Values indicate the average escape latency (in seconds). (B) Performance during the probe trial where the platform was removed. Values indicate the escape latency and percent time spent in the target quadrant. (C) Display of tracks of all groups during the probe trial. (D) Representative image of the brain taken after the MWM test. Values represent the mean ± SD, n = 10 in each group, **p < 0.01, ***p < 0.001 HI VS Sham; #p < 0.05, ### p < 0.001 HI + L-Cys VS HI; & p < 0.05, && p < 0.01 HI + L-Cys +AOAA VS HI + L-Cys.
