Bereitschaftspotential preceding eyelid blinks in Parkinson's disease.
Methods Ten PD patients in stages 1 and 2 of the Hoehn & Yahr classification were compared to 18 healthy controls. Artifact-free EEG segments of two seconds preceding the onset of the blink potential were averaged and analyzed, and the statistical significance of the measured amplitudes were evaluated by analysis of variance models. Results The presence of a BP in the PD patients was demonstr...
متن کاملPresence of Bereitschaftspotential preceding psychogenic myoclonus: clinical application of jerk-locked back averaging.
The method of jerk-locked back averaging was applied to six patients with clinically diagnosed psychogenic myoclonus. Five patients had a slow negative EEG shift corresponding to Bereitschaftspotential at the central region starting 0.7 to 2.1 seconds before the onset of the myoclonic jerk. One patient had no potential preceding the myoclonic jerk, whereas a small negative potential preceded th...
متن کاملDifferent effects of eyelid blinks and target blanking on saccadic suppression of displacement.
Displacements of visual stimuli during saccadic eye movements are often not noticed. We have demonstrated that saccadic suppression of image displacement can be eliminated by blanking the stimulus for a short period during and after the saccade (Deubel, Schneider, & Bridgeman, 1996). Here we report an experiment in which target visibility was interrupted after the saccade, either by distal targ...
متن کاملAge-related changes in human blinks. Passive and active changes in eyelid kinematics.
PURPOSE The authors analyzed eyelid kinematics in normal aging subjects to test the hypothesis that eyelid movements exhibit age-related changes and that blink disorders prevalent among the elderly, in turn, represent an outcome of normal aging processes. METHODS The electromagnetic search coil technique was used to study blinks in normal human subjects for each decade from 40 to 89 years. Bl...
متن کاملConjugacy of spontaneous blinks in man: eyelid kinematics exhibit bilateral symmetry.
PURPOSE To provide a quantitative description of the conjugacy of human eyelid movements during spontaneous blinks. METHODS Eyelid movements occurring during spontaneous blinks were recorded bilaterally using a modification of the electromagnetic search coil technique. In off-line analyses, covariation of amplitude, peak velocity, and duration of blink down phases were determined for the two ...
