Alpha asymmetry analysis results for the GAD and healthy control groups. (a) The average alpha power of the brain regions of HC participants and (b) GAD patients. The X-axis represents the brain regions, including the frontal, parietal, occipital, and temporal lobes of the left and right hemispheres. The Y-axis represents the average power density in the alpha band. The error bars represent the 95% confidence intervals. (c) The alpha asymmetry indices of brain regions in the HC and GAD groups. The X-axis represents the brain regions and groups. The Y-axis represents the alpha asymmetry index, which was calculated with the laterality coefficient (LC): (A − B)/(A + B), where A and B are the average alpha power densities of channels on the right and left hemispheres, respectively. The error bars represent the 95% confidence intervals.
