Abstract
Electrocorticographic spectral changes during movement show a behavioral inflection in the classic gamma band (30-70 Hz). We quantify this inflection and demonstrate that it limits classification accuracy. We call for the designation of a functionally defined band above it, which we denote the chi-band.
摘要
运动过程中的皮层脑电图频谱变化在经典γ波段（30 - 70赫兹）呈现出行为拐点。我们对这一拐点进行了量化，并证明它限制了分类准确性。我们呼吁在其上方指定一个功能定义的波段，我们将其称为χ波段。
