| Outline of Final Research Achievements |
The present study investigated the difference of efficacy and brain activated areas by different frequencies (30Hz、145Hz) during deep brain stimulation (DBS)of subthalamic nucleus (STN) in Parkinson’s disease (PD) monkey model. We performed H215O-PET to investigate the cerebral blood flow affected by “effective” (145 Hz) and “ineffective (30Hz) DBS when the behavioral test was performing. During the experiments, we developed the new PD model, new fixing device and the new behavioral tests. During the PET study, our preliminary data firstly showed that unilateral effective DBS may activate bilateral premotor areas, which means effective STN-DBS ameliorates not only the motor impairments, but also the preparation and initiation of the bilateral motor in PD state. This finding is helpful to achieve a deeper insight as to the mechanisms of DBS.
