Electrophysiological correlates of monocular dominant eye perception of verbal stimuli in emotional Stroop-test

Abstract

Peculiarities of monocular analysis of emotional words through dominant eye using emotional Stroop-test were investigated. The analysis revealed an increase of beta power in right handed subjects during the task with emotional words in case of dominant eye perception. In left handed subjects an increase in theta and beta power during the same task was observed. Disappearance of difference in latency of response between left and right hand when neutral information was perceived through leading eye was shown. There is no difference in the brain dynamics during tasks with real words and meaningless words in the case of dominant eye monocular stimulation that displays ignoring of irrelevant semantic context of stimuli in the processing of information that goes through the dominant visual channel.
