Abstract |
脳波反応から脳内制御モデルの成熟度を推定し、BMIリハによって「運動スキル獲得」が進むことを示した。また、BMIリハ中にBOLD MRIを計測し、頭頂連合野の活動性がBMI制御の成否を規定していることを見出した。一方で「報酬系を介した強化学習」の駆動は限定的と考えられた。さらに、神経筋電気刺激の特定パラメータが視床や体性感覚運動皮質の活動を賦活することを明らかにし、運動反応駆動式の神経筋電気刺激は体性感覚運動皮質におけるHebb的可塑性を誘導しうることが示された。
As the number of EEG-BMI trials was increased, the initial EEG response prior to the onset of BMI control, an analogue of motor-related cortical potentials, was gradually increased. The data suggests feedforward model of BCI control was maturated in a trial by trial manner. In parallel to such skill acquisition process, the researcher further explored alternative learning/plasticity process using f-MRI. The parietal-temporal regions were identified to determine successful BMI control, suggesting visuomotor adaptation/computation is a considerable key to facilitate BMI use. The subcortical reward systems were not activated in the current BMI setting.
Gamified BMI may promote reward-based reinforcement learning. Finally, the researcher tested what parameters of neuromuscular electrical stimulation actuates peripheral sensory nerves to send facilitatory signals to the cortex. The study revealed that wide pulse, high frequency stimulation activated thalamus and sensorimotor cortex.
