Indicators of rats tested in the EPM, (median, intervals of change): total distance traveled (a), total number of transitions (b); latency of the first entry into the closed arm (c); the ratio of the time spent in the closed (CA) and open (OA) arms of the maze (d), the average speed in the OA (e). * the difference with the control group is significant; # the difference with the group receiving HFCD is significant, p < 0.05, Mann-Whitney test; ¤ the difference with the first test is significant, the Wilcoxon test for pairwise comparisons. The bracket above the bars denotes significant dependence on the factors: “test” (T), “diet” (D), “tyrosine” (Tyr), “tryptophan” (Trp) and their combinations, p < 0.05, 3-way ANOVA. The number of animals in the groups was 8.
