From: EEG reveals brain network alterations in chronic aphasia during natural speech listening
Methodological workflow. (a) EEG is recorded while the participants listen to a story, and functional connectivity is extracted from the recorded signals. On the connectivity matrix, purple bar: left hemisphere; green bar: right hemisphere. (b) Group differences and correlations with behavioural test scores were assessed. (c) Graph measures were computed and compared between groups within the frequency bands with significantly different network patterns. Blue: HC; red: PWA. On the topography, blue: HC > PWA, red: PWA > HC. (d) Targeted node-attack to investigate the network distribution in both groups. Blue: HC; red: PWA. (e) Diagnostic accuracy analysis with implementation of a support vector machine classifier.
