Our research team has been awarded an $8M research grant from the National Science Foundation (NSF) to continue our development on a fully implantable BCI system. The goals of this project will be to develop and test bi-directional (BD), electrocorticogram (ECoG)-based brain-computer interface (BCI) system in people with paraplegia due to SCI. This system is envisioned to restore both brain-controlled walking and leg sensation after SCI. The project will also aim to develop an implantable prototype that will undergo animal testing for safety so as to eventually obtain FDA approval for human testing.
