Outline of Final Research Achievements

The working memory system involving the body schema that represents the geometry of the body with respect to the external environment, for example, obstacles and/or objects close to the body, could have a key role in regulating stepping movements during locomotion. This study demonstrates the importance of memory-guided limb control for stepping over an obstacle during locomotion, and the memory-guided limb movements in stepping over an obstacle were impaired in Alzheimer’s disease (AD) model mouse.
We used the triple transgenic (3xTg) mice to examine the effects of memory deficits in terms of tripping and contact with obstacles. We found that the frequency of contact of the hindlimbs during an obstacle avoidance task increased significantly in 10-13 month-old 3xTg (Old-3xTg) mice compared with
control mice. Furthermore, using an interrupted obstacle avoidance task, we found that Old-3xTg mice showed severe deficits in their working memory.
