[Relationship between evoked potential parameters and perception].
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.
