| Outline of Final Research Achievements |
Parkinson’s disease (PD) is one of the major human movement disorders in terms of prevalence and morbidity. Our research aim to employ abnormal oscillatory and synchronised activity across populations of neurons recorded from basal ganglia as a biomarker for controlling optogenetic deep brain stimulation. Our increased understanding of how different patterns of population activity are associated with different forms of movement disorders raises the possibility of improving DBS through closed loop stimulation. In closed-loop mode, stimulation could be titrated using a biomarker such as a particular pattern of abnormal activity to determine when and how much stimulation is necessary. In this study we examined a dozen of optogentics tools in marmosets and mice to determine which one is the best for our purpose. By using it, we succeeded in simultaneous recording and optogenetic neural modulation. We moved to assemble optogenetic deep brain simulation system.
