Effects of oleuropein on spatial learning and memory in diabetic rats. (a) The escape latency of rats in the Morris water maze on days 1, 2, 3, and 4. (b) The number of crossing intersections of the platform quadrant in Morris water maze test. (c) The time spent by rats in the target quadrant in the Morris water maze test. (d) The swimming speed of the rat in the Morris water maze test. Each set contains data from 3 samples tested independently; LSD test was used for multiple comparisons. ^∗∗p < 0.05 vs. control group and ^##p < 0.05 vs. STZ group.
