Beyond the gamma band: the role of high-frequency features in movement classification

IEEE Trans Biomed Eng. 2008 May;55(5):1634-7. doi: 10.1109/TBME.2008.918569.

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.
