| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, the effect of neurofeedback training on brain activity during motor imagery was evaluated by functional magnetic resonance imaging (fMRI). The training was performed for 5 days using near-infrared spectroscopy (NIRS). During training sessions, feedback information was extracted from the brain activity which was measured online while users performed motor imagery of right hand. On 3 out of 5 subjects, brain activations at supplementary motor area (SMA), primary motor area (M1) and cerebellum were localized after training. Furthermore, analysis of BOLD signal in specific volume of interests (VOIs) showed that peak and integral values during motor imagery became smaller after training on 2 of these 3 subjects. In contrast, it was shown by our NIRS study that the integral values of oxy-hemoglobin signal measured by NIRS during motor imagery on these 3 subjects were increased after feedback training. | |
