我们证明了从硬膜下电极阵列使用较高频谱频率（76-200 Hz，或“卡氏指数”）的皮层电图信号功率进行实时皮层映射的可行性。使用简单的基线和手部运动测量，在8个人中离线绘制手部面积。在一名患者中，手感觉运动皮层在握手过程中被在线识别。我们建议，这种高频成分的皮层脑电图提供了一个通用的，可靠的，临床上有用的相关的局部皮层功能。(c)2007爱思唯尔公司All rights reserved.
We demonstrate the feasibility of real-time cortical mapping from arrays of subdural electrodes using the electrocorticographic signal power in the higher spectral frequencies (76-200 Hz, or "chi-index"). Hand area was mapped offline in eight individuals using brief baseline and hand-movement measurements. In one patient, hand sensorimotor cortex was identified online during a handshake. We propose that this high-frequency component of the electrocorticogram provides a generic, reliable, clinically useful correlate of local cortical function. (c) 2007 Elsevier Inc.
