Abstract

Evoked electrocortical activity appearing during rhythmic stimulation and its correlation with the level of expectancy of the signal next in turn (expressed in values of reaction time), were studied in nine grown up subjects. Reorganization of auditory evoked potentials (EPs), mostly expressed during reactions preceding the stimulus or coinciding with it occurs at motor responses to rhythmical stimuli. The character of correlation between EPs and perception is satisfactorily explained by a cyclic model of the sensory information processing. Adaptive behaviour is provided by the cyclic processes promoting engrams formation and adequate pretuning to probable events.

摘要

在九名成年人中研究了节律性刺激期间出现的诱发皮层电活动及其与下一个信号预期水平(以反应时间值表示)的相关性。听觉诱发电位(EPs)的重组主要表现在刺激前或与刺激同时发生的反应中,在对节律性刺激的运动反应中出现。EPs与感知之间的相关特征通过感觉信息处理的循环模型得到了令人满意的解释。适应性行为由促进记忆痕迹形成和对可能事件进行适当预调谐的循环过程提供。
