摘要: <正> 第一个描記人类脑电图的貝格尔(H. Berger)便观察到頻率每秒20次左右的β波显然較每秒10次左右的α波更加与思維(心算)有关。1935年有人謂心算或感觉想象等思維活动使α波阻抑,以后許多作者都认为α波(枕叶α波)阻抑显然是思維活动的指标。虽然个别作者曾观察到思維时α波未必阻抑,但α波阻抑与思維(默讀

Abstract: 1. An experiment was performed to investigate the correlation between α-blocking and mental activity (mental calculation) with the automatic analysing techniques etc. 166 subjects, 49 males and 117 females of 6 to 40 years of ages, were employed in the study. Subjects were specially selected, whose resting EEG's revealed a percent time α orθ(α) of more than 80. Results showed that there was a negative correlation between occipital α-blocking and mental activity.2. Automatic analysing techniques showed that during mental activity only 20% of the subjects were found to give diffusely α-blocking over the whole cortex and no subject was found to give only occipital α-blocking.3. Information processing of the occipital α-waves (driving response elicited by "threshold" photic stimulation) was not disturbed by mental calculation in 94.4% of the cases.4. Kappa waves of 6—8 c/sec, were observed in the frontal region during mental activity. These waves were not related to α-waves and eye-flutter movements.
