Somatosensory EPs and reaction time were recorded simultaneously in 7-8 years old children when they solved perceptual tasks with 4 levels of complexity. The obtained data confirm the studies, suggesting the lack of connection between perceptual processes and amplitude-temporal parameters of early and late EP components in the projection cortical area. The method of recording summary evoked activity, while allowing to determine the degree of involvement of nervous elements or structures in the response to sensory signals, does not reveal spatial-temporary patterns of impulse activity in the cortical and cortical-subcortical-cortical loops providing for perception. The idea that dynamics of EP parameters produced by multiple sensory signals reflects the process of entry into memory and read out of stored information may be efficient for the understanding of mechanisms underlying higher cortical functions.
在7 - 8岁儿童解决4种不同复杂程度的感知任务时,同时记录体感诱发电位(Somatosensory EPs)和反应时间。所得数据证实了相关研究,表明在投射皮层区域,感知过程与早期和晚期诱发电位成分的波幅 - 时间参数之间缺乏联系。记录总和诱发活动的方法,虽然能够确定神经元件或结构对感觉信号反应的参与程度,但无法揭示在皮层及皮层 - 皮层下 - 皮层环路中为感知提供支持的冲动活动的时空模式。由多个感觉信号产生的诱发电位参数动态反映进入记忆和读出存储信息的过程这一观点,可能有助于理解高级皮层功能的潜在机制。
