N2 - We present a feasibility study of inducing plasticity of the corticospinal tract to the flexor carpi radialis muscle by using EEG based Brain-Computer Interface (BCI) technology. The mental task that drives the proposed asynchronous BCI is hand motor imagery, which when detected activates a functional electrical stimulation induced matching movement. Tests on four healthy subjects show that the BCI can be asynchronously driven with a precision in the range of 0.66- 0.92 and a sensitivity 0.81-0.94. Alterations in cortical excitability prior, immediately after and 30 minutes following the BCI intervention was quantified by the amplitude of the motor evoked potentials (MEPs) induced by transcranial magnetic stimulation. Preliminary results show that the BCI intervention did not induce consistent alterations of MEP size in the target muscle. However the greater variability of MEPs following the intervention indicates that the motor cortex is undergoing changes.
