| abstractText | The Morris water-escape task is an extensively used experimental paradigm to assess the spatial discrimination performance and effects of brain lesions and drugs on this performance. In the first experiment, we compared the acquisition of this task by different strains (CFW1, BALB, NMRI, and C57BL) of mice and their performance in a probe trial. In a second experiment, C57BL mice were tested in Morris mazes where black and white tanks were combined with white or black platforms to investigate if and how the contrast between the tank and the platform affects the performance of the mice. In addition, four brightness conditions were compared to investigate whether or not the degree of brightness of the tank itself affects the learning performance. The results of these experiments indicated that 1. mice could readily learn the Morris task, 2. one of the contrast conditions affected the swimming speed, 3. the maze brightness per se did not affect water escape performance at all, and that 4. the swimming speed can strongly bias the outcome of Morris water-escape experiments in mice. |
