1. Cognitive evoked potentials related to visual perception of motion in human subjects

Creator:
Kuba, M., Kremláček, J., and Kubová, Z.
Type:
article, model:article, and TEXT
Subject:
cognitive evoked potentials, P300, visual motion stimulation, and visual perception of motion
Language:
English
Description:
A method was tested for simultaneous recordings of evoked potentials from the secondary visual cortex (medio- temporal) and from the brain cognitive areas (fronto-central). Visual moving stimulations with cognitive tasks seem to be suitable for combined examination of visual motion perception and cognitive processes based on the magnocellular system activity. This arrangement enhances the analysis of visual information processing and evaluation of central nervous system functions.

3. Motion-reversal visual evoked responses

Creator:
Kuba, M., Toyonaga, Naoto, and Kubová, Z.
Type:
article, model:article, and TEXT
Subject:
visual evoked responses, VEPs, visual motion stimulation, and motion-reversal
Language:
English
Description:
Motion-reversal visual evoked responses (VERs) have remarkable waveform variability. In our opinion this is caused by the alternative predominance of either motion or pattem-onset/offset related components. The motion dependent component of motion-reversal VER closely resembles motion-onset VER (main negative peak with the latency of about 170 ms), the first positive peak (with the latency of about 100 ms) corresponds to the pattern-onset component and the second non-constant positive peak (with the latency of about 130 ms) seems to be identical with the pattern-offset positivity. The differences in expression of these components are dependent on some stimulus characteristics (mainly on the contrast of a structure, velocity of motion, retinal localization of the stimulus) and on substantial differences in the sensitivity of subjects to motion stimulation.
