Figure 5.

Time in target quadrant during Morris water maze testing. The time in target quadrant was measured during the three day retention phase. The p50−/− mice showed a highly significant (P = 0.009) decrease relative to the p50+/+ mice for this measurement on the 8th day of testing (i.e., first day of the retention phase). The experiment was conducted for 2 minutes (120 s) and so the dashed line drawn at 30 seconds indicates chance levels.
