Abstract
In an investigation of the interhemispheric coherence (IhC) model for eye movement desensitization and reprocessing (EMDR) bilateral eye movement (BEM) effects, 30 participants were exposed to a stationary dot, a blinking red/green dot, or saccadic BEMs during the contemplation of a positive emotional memory. Electroencephalographies (EEGs) were measured afterward during an eyes-closed processing stage. Analyses revealed no significant IhC enhancement for the BEM condition but significant increases in Delta and Low Beta EEG intrahemispheric BEM coherence in the right and left frontal areas, respectively, and a trend increase in Right Frontal Low Beta BEM coherence. LORETA neuroimaging was employed to visually present significant amplitude changes corresponding to observed coherence effects. The functional significance of these intrahemispheric coherence effects is presented and a cortical coherence extension of the IhC model is suggested.
