Abstract

Alpha waves are electroencephalogram discovered by Hans Berger in 1929 and have been studied by many researchers. Recently the amplitude and the phase of alpha waves attract attention, and various studies are reported. So far the alpha waves are not concretely modeled to explain how they are constituted. In this paper, we analyze the phase of alpha waves for their future modeling. As pre-processing, we extract alpha wave data from EEGs and divide the data into alpha wave constituent waves. Analyzing the feature quantity of the alpha wave constituent waves, it turns out that the amplitude and the wavelength of alpha wave constituent waves are correlated with a constant time delay.
α波的组成与相位分析
阿尔法波是汉斯·伯杰于1929年发现的脑电图,许多研究者对其进行了研究。近年来,对α波的振幅和相位的研究引起了广泛的关注,并有各种各样的研究报道。到目前为止,α波还没有具体的模型来解释它们是如何构成的。在本文中,我们分析了α波的相位,以便将来对其进行建模。作为预处理,我们从脑电图中提取α波数据,并将数据划分为α波组成波。分析α波组成波的特征量,发现α波组成波的振幅和波长与一个恒定的时滞相关。
