A method for the projection of EEG data on the brain surface is proposed. The EEG data are obtained during the performance of mental tasks and represented as probability maps of power and coherence changes with respect to the averaged EEG at rest. The morphological data are obtained from 3D reconstructions of the brain by means of serial slices provided by an MRI scanner. Before scanning the positions of the EEG electrodes were marked by dummy electrodes of plexiglass filled with a contrast medium. Changes of power are color-coded and entered at the respective electrode positions, changes of coherence between the respective positions. The applicability of this procedure in the fields of psychology, psychiatry and neurology is discussed.
提出了一种将脑电图（EEG）数据投影到脑表面的方法。EEG数据是在执行心理任务期间获得的，并表示为相对于静息时平均EEG的功率和相干性变化的概率图。形态学数据是通过MRI扫描仪提供的连续切片对大脑进行三维重建而获得的。在扫描之前，用填充有造影剂的有机玻璃虚拟电极标记EEG电极的位置。功率变化用颜色编码，并输入到各个电极位置，即各个位置之间的相干性变化。讨论了该程序在心理学、精神病学和神经病学领域的适用性。
