LTP recordings after high-frequency stimulation (HFS) to the perforant path (PP) in different groups. (A) Sample traces recorded from the hippocampal DG area. The upper panel shows the records before HFS while the lower panel shows the records after HFS to PP. (B) Percentages of population spike amplitude, (C) percentages of fEPSP slope, and (D) percentages of the area under the curve. Data were analyzed by repeated-measures two-way ANOVA followed by Tukey's post-hoc test. Data are presented as mean ± SEM, (n=5). HE: Hepatic encephalopathy, TQ: Thymoquinone. *** P<0.001 vs control group, # P<0.05, ## P<0.01, and ### P<0.001 vs HE group
