UNASSIGNED: In previous studies, @entity2704 @entity1 showed abnormalities in @entity158 -related evoked responses, as reduced @entity734 to repetitive stimulation. In this study, we aimed to apply a novel analysis of EEG bands synchronization and directed dynamical influences under @entity158 stimuli in @entity2704 @entity1 compared to non- @entity2704 healthy volunteers. Thirty-one @entity5330 outpatients (MIGR) were evaluated and compared to 19 controls (CONT). The right hand was stimulated by means of 30 consecutive CO2 laser stimuli. EEG signal was examined by means of Morlet wavelet, @entity7158 ( @entity7158 ), and Granger causality (GC), and the statistically validated results were mapped on the corresponding scalp locations. The vertex complex of averaged laser-evoked responses (LEPs) showed reduced @entity734 compared to CONT. In the prestimulus phase, enhanced @entity7158 in the 0, 5-30   Hz range was present in MIGR and CONT between the bilateral temporal-parietal and the frontal regions around the midline. @entity2704 @entity1 showed an anticipation of EEG changes preceding the @entity158 stimulation compared to CONT. In the poststimulus phase, the same cortical areas were more connected in MIGR vs CONT. In both groups of @entity1 and CONT, the @entity734 index was negatively correlated with the GC scores. A different pattern of cortical activation after @entity158 stimulation was present in @entity2704 . The increase in cortical connections during repetitive @entity158 stimulation may subtend the phenomenon of LEPs reduced @entity734 . Brain network analysis may give an aid in understanding subtle changes of @entity158 processing under laser stimuli in @entity2704 @entity1 .
