behavior/neurological
• take significantly longer to locate the hidden platform in the Morris Water Maze task than controls, however the ability to find the hidden platform improves over test sessions
• in a probe trial in which the platform is removed following training, mutants spend significantly less time searching for the platform in the target quadrant, however exhibit normal performance in the visible platform task
|
• fall off more quickly from a rotating rod than controls at 5, 10, and 15 rpm and the retention time does not improve in mutants across trails of training, however exhibit normal grip strength, spontaneous motor activity, and walking patterns
