Abstract EN
Electrocorticography (ECoG) has been demonstrated as a promising neural signal source for developing brain-machine interfaces (BMIs).
However, many concerns about the disadvantages brought by large craniotomy for implanting the ECoG grid limit the clinical translation of ECoG-based BMIs.
In this study, we collected clinical ECoG signals from the sensorimotor cortex of three epileptic participants when they performed hand gestures.
The ECoG power spectrum in hybrid frequency bands was extracted to build a synchronous real-time BMI system.
High decoding accuracy of the three gestures was achieved in both offline analysis (85.7%, 84.5%, and 69.7%) and online tests (80% and 82%, tested on two participants only).
We found that the decoding performance was maintained even with a subset of channels selected by a greedy algorithm.
More importantly, these selected channels were mostly distributed along the central sulcus and clustered in the area of 3 interelectrode squares.
Our findings of the reduced and clustered distribution of ECoG channels further supported the feasibility of clinically implementing the ECoG-based BMI system for the control of hand gestures.
