Electro-oculagraphic, photo-oculographic, and magnetoelectro-oculographic methods were used to study and to compare the accuracy of 10 degrees saccadic movements of the eyes in dependence on their direction to the right, to the left, upwards and downwards. Leftward saccades in right-handers and rightward saccades in left-handers proved to be more accurate(More)
To be healthy and feel well does not evoke any particular attention of man. It is held as something natural and is used as a basis for other interests and activities. Disorders of health, in contrast, are noticed by a heightened arousal as they represent distress and/or danger of suffering and threatening of life. This may be one of reasons why there exist(More)
The saccadic eye movement-related potentials (SEMRPs) were recorded over various brain areas in a group of righthanders while they performed saccades to visual stimuli appearing either at regular or at irregular time intervals. The premotion positivity, motion execution component and lambda responses were of shorter latencies and lower amplitudes over the(More)
The exactness of saccadic eye movements to the right and to the left and changes in evoked potentials related to these eye movements were analyzed in 50 university students with marked righthandedness and normal vision, aged from 18 to 24 years (18 males, 32 females). The saccades to the left were found to be more exact than those to the right, which(More)
Optokinetic nystagmus (OKN) pursuit phase velocity oscillations were studied in seven undergraduates during repeated 4 min presentation of optokinetic stimuli. The following variable parameters of the stimuli motion were used with each subject: horizontal direction, angular velocity (AV), and frequency-to-velocity ratio. AV of the OKN pursuit phases was(More)
