Table 2. Platform crossings for each rat by group during the probe test.
| Groups | Platform crossings (number of times) | |||||||||
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | |
| Control | 2 | 1 | 1 | 4 | 0 | 1 | 2 | 0 | 2 | 0 |
| Al* # | 1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 |
| MF | 2 | 1 | 1 | 0 | 0 | 1 | 2 | 1 | 3 | 0 |
| MF+Al* # | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 |
During the probe test at the sixth day after finishing the acquisition task, each rat was allowed to swim freely for 30 s, the number of crossings through the target position was recorded for each rat by group (10 rats per group). Rank sum tests revealed no significant differences in platform crossings between the Al and MF+Al groups and between the control and MF groups.
