The EEGs of 76 children (6--9 years of age) were classified into five types for the occipital regions (O1 and O2) and into seven types for the central regions (C3 and C4) by the method of EEG pattern discrimination (Sato, Ono et al., 1977). The five types of EEG patterns observed in the occipital regions were: (1) low frequency alpha wave of about 8--9 Hz, (2) Hz alpha wave, (3) low frequency alpha and theta wave, (4) 10 Hz alpha wave and theta wave and (5) irregular wave patterns, while two more types, (6) the low pass and (7) theta wave types, were observed in the central regions. These same types were also observed in the EEGs of 41 adults (20--25 years of age). The amount of difference between the above five and seven types in children and adults were obtained by the generalized (Mahalanobis') distances. In the occipital regions, the percentage frequency of the alpha wave type was the highest followed by that of the alpha and theta wave type, while the frequency of the alpha and theta waves type was the highest in the central regions, followed, next and third in order by the low pass type and the alpha type, respectively.
采用脑电图模式判别方法（佐藤、小野等人，1977年），将76名儿童（6 - 9岁）枕叶区域（O1和O2）的脑电图分为五种类型，中央区域（C3和C4）的脑电图分为七种类型。在枕叶区域观察到的五种脑电图模式为：（1）约8 - 9赫兹的低频阿尔法波，（2）赫兹阿尔法波，（3）低频阿尔法波和西塔波，（4）10赫兹阿尔法波和西塔波，以及（5）不规则波形，而在中央区域还观察到另外两种类型，即（6）低通型和（7）西塔波型。在41名成年人（20 - 25岁）的脑电图中也观察到了相同的类型。通过广义（马氏）距离得出儿童和成年人上述五种和七种类型之间的差异量。在枕叶区域，阿尔法波型的频率百分比最高，其次是阿尔法波和西塔波型；而在中央区域，阿尔法波和西塔波型的频率最高，其次依次是低通型和阿尔法波型。
