Abstract

Data are presented which show that background electric activity of the human brain is reduced by visual stimulation. Occipital EEG amplitude decreases 5-15% for all frequencies analyzed (0.2-40 Hz) upon pattern stimulation. The reduction is stimulus-specific, i.e. is the strongest for stimuli that activate a large number of visual cortical neurons.

摘要

所呈现的数据表明，视觉刺激会降低人类大脑的背景电活动。在图案刺激时，枕叶脑电图的幅度在所有分析频率（0.2 - 40赫兹）下都会降低5 - 15%。这种降低是刺激特异性的，即对于激活大量视觉皮层神经元的刺激最为强烈。
