Figure 1.

Effects of Royal jelly (RJ) contained food on performance during the spatial acquisition of Morris water maze test in rats with intracerebroventricular injection of streptozotocin. Schematic diagram of tank and site of the platform (a). The escape latencies (b), the path length (c), and the swim speed (d) at different days to reach the platform. Each point represents the day mean ± SEM of 4 swims. For latency and path length, lower numbers indicate better performance (*P < 0.05 and **P < 0.01 with respect to the sham group, †P < 0.05 significant difference between the lesion and the lesion-RJ groups; n = 9).
