[Effect of emotional tension on the spatial-temporal organization of prestimulus potentials of the neocortex of a human operator on the recognition of a meaningful photic stimulus].
Analysis of psychometric data at recognition of digital stimuli in a state of high emotional stress allowed to single out two groups of subjects--with improved and with worsened quality of activity. It is shown that the structure of intrahemispheric cross-correlation coefficients before states with a short time of recognition, a long time and with nonrecognition of the stimulus, appearing in operative quietness, is preserved in emotional stress for subjects with a better quality of activity and changes for half of the pairs of intrahemispheric leads in subjects with worsened quality of activity.
