用于恢复运动和感觉的双向脑机接口必须同时记录神经信号并传递皮层刺激。这带来了挑战,因为刺激伪影可能比神经信号强几个数量级。在本文中,我们提出了一种新的基于子空间的方法来去除皮层电刺激伪影。我们演示了我们的方法在实验记录的脑电图数据上的实际应用,其中伪影被高达$30-40\ mathm {d}\ mathm {B}$抑制。我们的方法计算简单,但它取得的结果优于最先进的方法。
Bi-directional brain-computer interfaces for the restoration of movement and sensation must simultaneously record neural signals and deliver cortical stimulation. This poses a challenge since stimulation artifacts can be orders of magnitude stronger than neural signals. In this article, we propose a novel subspace-based method for the removal of cortical electrical stimulation artifacts. We demonstrate the practical application of our approach on experimentally recorded electroencephalogram data, where artifacts were suppressed by as much as $30-40\mathrm {d}\mathrm {B}$. Our method is computationally simple, yet it achieves superior results to the state-of-the art methods.
