The analysis of the late positive wave (component P300) of an averaged evoked potential, recorded to visual stimuli in different experimental situations has shown that local activation of the cerebral cortex during conscious experience (Pavlovian "light spot") is of a dynamic nature and is determined by signal significance of stimuli and predominant voluntary activity. In cases when it is necessary to decide on the choice of reaction anterior areas of neocortex are activated. If the function of perception is dominating the local activation essentially occurs in corresponding cortical area at which the perceived stimulus is timed. The cortico-thalamo-cortical mechanism of focused attention and its role in providing for conscious human experience is discussed.
对在不同实验情境下记录的视觉刺激诱发的平均诱发电位晚期正波（成分P300）的分析表明，在有意识体验（巴甫洛夫式的“光点”）期间大脑皮层的局部激活具有动态性质，并且由刺激的信号意义和主要的自主活动决定。在需要决定反应选择的情况下，新皮层的前部区域会被激活。如果感知功能占主导地位，局部激活主要发生在感知到刺激的相应皮层区域。本文讨论了集中注意力的皮质 - 丘脑 - 皮质机制及其在人类有意识体验中的作用。
