| Outline of Annual Research Achievements |
My main focus this year was to identify predictors of finger tapping (spontaneous and subjective pacing of one-second) in both Parkinson's patients (PD) and healthy control patients. Results showed that the Trail Making Task part A (TMT-A) could be a better cognitive measure than the Montreal Cognitive Assessment (MoCA) in predicting finger tapping. This paper is now in preparation for getting published. As for my study about explicit and implicit timing, I have written the program for the data collection with PD patients, presented to the doctors that I will be collaborating with, and gotten IRB ethical approval for collecting data at Showa University Hospital.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
This year, the progress on my project about explicit and implicit timing in Parkinson's disease has been slower than expected due to delays in collaboration. Sorting out the schedule with the doctors who I am collaborating with, and getting the IRB ethical review board to approve my experiments to be conducted with Parkinson's patients took more time than I had planned.
|
| Strategy for Future Research Activity |
Now that I have gotten the IRB ethical approval at Showa University Hospital, data collection will begin. I will be recruiting approximately 60 patients with Parkinson's disease. Moreover, once I know that the planned experiment works with patients with Parkinson's disease, and no modifications is needed for the script, I will also be collecting data from an age-matched healthy control group at Keio University. Moreover, I will be collaborating with other researchers for other experiments about pre-pulse inhibition in patients with Parkinson's disease.
|
| Causes of Carryover |
There are two main reasons why I have carried over the budget. The first is that the ethical review approval for the research I planned to conduct at Showa University Hospital took longer than expected and therefore, I could not recruit participants and pay for their participation to my experiment. Secondly, one of the papers I planned to publish did not go through in time and therefore, it will be published in this academic year.
