The spontareous and rhythmical signals of the brain are abtained from the normal EEG multichannel recorder and analysed by the system based on FFT. The results are drawn in the head model. From the clinical applications to the diagnosis of brain illneses, this system is very helpful to the docters. 脑电功率谱地形图 脑电波形图 频谱分析 模式识别 topographic drawing of EEG power spectra wave diagram of EEG frequency spectrum analyses model-distinguishing 1991-02-01 2021-04-01 2
