| Outline of Final Research Achievements |
BDNF level in the peripheral blood was measured by ELISA using microarray. BDNF related polymorphism on gene was also measured from oral mucosa by PCR. Data received was then classified in accordance with the previous findings and gene database. A number of persons with polymorphism was actually much lower than that reported previously, thus a sufficient statistical analysis has not been given to study correlation between BDNF and behavior in motor learning. On the contrary, in a more macroscopic view, I found a nice association between brain structural change and motor performance. Primary motor cortex and hippocampu increased their volume at Day 1 and Day2, and the extent of volume increase explained following motor learning process in horizontal reaching paradigm. Integrity change in the corticospinal tract was also a predictor of following learning process. These study suggests that brain structural change is not only a foot print, but also a driving force of motor learning.
