Electroencephalography resting?state networks in people with Stroke

Introduction The purpose of this study was to characterize resting-state cortical networks in chronic stroke survivors using electroencephalography (EEG). Methods Electroencephalography data were collected from 14 and 11 neurologically intact participants while they a relaxed, resting state. EEG power normalized reduce bias used as an indicator network activity. Correlations orthogonalized activity measure functional connectivity between regions. Results We found reduced the alpha (p < .05; p = .05) beta .03) bands after gamma .031) band increased. Asymmetries, driven by reduction lesioned hemisphere, also noted .001) stroke. Conclusion These findings suggest that lesions cause alteration more local (higher frequency), asymmetric networks. Understanding changes could be combined with controllability models identify (and target) alternate brain states impairment.
