Diffusion spectral imaging modules correlate with EEG LORETA neuroimaging modules

摘要

The purpose of this study was to test the hypothesis that the highest temporal correlations between 3‐dimensional EEG current source density corresponds to anatomical Modules of high synaptic connectivity. Eyes closed and eyes open EEG was recorded from 19 scalp locations with a linked ears reference from 71 subjects age 13–42 years. LORETA was computed from 1 to 30 Hz in 2,394 cortical gray matter voxels that were grouped into six anatomical Modules corresponding to the ROIs in the Hagmann et al.'s [ ] diffusion spectral imaging (DSI) study. All possible cross‐correlations between voxels within a DSI Module were compared with the correlations between Modules. The Hagmann et al. [ ] Module correlation structure was replicated in the correlation structure of EEG three‐dimensional current source density. EEG Temporal correlation between brain regions is related to synaptic density as measured by diffusion spectral imaging. Hum Brain Mapp, 2011. © 2011 Wiley‐Liss, Inc.
