Novel object recognition task (NORT). Contact time with the novel and familiar objects (a), discrimination index (b), total distance (c), and total number of rearings (d) displayed by the four experimental groups (sham oil, n = 11; sham n-3 PUFA, n = 15; sap oil, n = 9; sap n-3 PUFA, n = 13). Asterisks indicate the level of statistical significance of the comparisons between contact time (s) with the novel vs. familiar object (a) and discrimination index between groups (b): **p ≤ 0.01, ***p < 0.001. Hashes indicate the statistical significance of diet effect (c, d): ##p < 0.01, ###p < 0.001. Post-hoc comparisons between trials in c (habituation vs. training or test trials, p < 0.001; training trial vs. test trial, p < 0.05) and d (habituation vs. training or test trials, p < 0.001; training trial vs. test trial, p < 0.01)
