Effects of the surgery on behaviour (A). Latency to eat food from the buried food test between the BCCAL (n = 6) and sham-operated rats (n = 6) at four weeks and eight weeks after surgery. (B) Open field test, (B1) total distance travelled, (B2) time spent in the centre, (B3) freezing time, and (B4) latency to the centre between the BCCAL and sham-operated group at four weeks and eight weeks after surgery. (C) Y-maze test, (C1) total number of arms visited, (C2) entries to the novel arm, and (C3) duration in the novel arm between the BCCAL and sham-operated rats at 4 weeks and 8 weeks after surgery. * indicates p < 0.05 versus sham group; # indicates p < 0.05 versus week 4 after the surgery. Values are expressed in mean ± standard error of the mean (SEM). Abbreviation: BCCAL: bilateral common carotid artery ligation.
