Effects of LPS on the natural and learned behaviours. (A) Latency to eat food from the buried food test, (B) open field test, (B1) total distance travelled, (B2) time spent in the centre, (B3) freezing time, (B4) latency to the centre, (C) Y-maze test, (C1) total number of arms visited, (C2) entries to the novel arm, and (C3) duration in the novel arm by surgical types and LPS administrations at 24, 48, and 72 h post-LPS (n = 10). * indicates p < 0.05, ** indicates p < 0.001 versus BCCAL + saline, and # indicates p < 0.05, ## indicates p < 0.001 versus value at the previous time point. Values are expressed in mean ± standard error of the mean (SEM). Abbreviation: LPS: lipopolysaccharide; BCCAL: bilateral common carotid artery ligation.
