Minimally invasive BCI achieves precise movement control in tetraplegic patients, suggesting improved quality of life.
Key Points
The system improved control for tetraplegic patients, achieving Fitts' ITRs of 36.7 bpm in two-dimensional tasks, indicating significant advancements in BCI technology.
Epidural neural signals effectively represented both contralateral and ipsilateral movements, revealing a remarkable bilateral representation structure for limb control.
Steady performance over 6 months and high hit rates exceeding 91% demonstrate the reliability and usability of this long-term BCI solution.
Neural recordings remained stable for over 18 months, showing the potential for safe home use without the need for recalibration.
