title: Study of the alpha frequency band of healthy adults in quantitative EEG.
abstract: The qEEG of the alpha band in 115 healthy adults, and for comparison the SPM of 244 patients, were studied. The alpha band was divided into three subgroups: alpha 1 (8-8.9Hz), alpha 2 (9-10.9Hz) and alpha 3 (11-12.9Hz). This method could both demonstrate the dominant rhythm of healthy adults and discover alpha slowing. The distribution of the level of power and percentage of frequency in alpha 1, 2 and 3 varied on different head regions. While the distribution of alpha 1 was the same as the theta and delta bands, there was a trend toward abnormally high power of alpha 1 and theta bands in patients.
