Dynamic Frequency and Multi-site Cortical Stimulation for Inducing Artificial Somatosensation: A Preliminary Study

摘要

Eliciting artificial somatosensation using brain stimulation has become one of the most essential techniques in closed-loop brain machine interface (BMI) system to control robotic limb. To date, however, clinical researchers have struggled to precisely control the quality of induced artificial somatosensation due to limited stimulation methods. Here, we developed dynamic frequency and multi-site cortical stimulation methods using clinically approved cortical stimulators. Additionally, we report results of our tests on one patient to validate these techniques.
