| Research Abstract |
It is common knowledge that exercise, especially muscle activities of inferior limbs, can have an adverse effect on cognitive function of the brain. In this research, I investigated effects of muscle activities on cellular or molecular mechanism involved in maintaining and progress of the brain function. In order to inhibit the antigravitational muscle activities, I used hindlimb-suspended rats. The results from water maze test suggest that learning and memory capacity might be impaired by the hindlimb suspension. Furthermore, 2-dementional electrophoresis revealed that the hindlimb suspension could alter the protein expression levels and/or the modification of proteins in the hippocampus, involved in cellular protection, cell death, neurogenesis, neural activities and formation of the neuronal circuit.
