Decline in the performance of mice injected with Rib in the Morris water maze test. Conditions for the injection of Rib at different doses were the same as those given in Figure 5. The length of time mice took to find the hidden platform was recorded as latency of escape during each of the eight training days (a). The percent of the searching time and distance spent in the quadrant where the platform was removed during the probe trial is shown in b. A visual platform test was also performed, and the length of time mice took to find the platform was recorded as latency of escape (c). All values are expressed as means±S.E.M. *P<0.05
