Default Mode Network Electroencephalographic Activity in Depression and Depression Subtypes - Dataset

The relationship between the electroencephalographic activity of the default mode network (DMN) and depression symptoms was investigated in a community sample of 100 people. DMN activity was observed by comparing recordings taken over cortical areas associated with the network with non-DMN areas. Clinically significant depression was significantly correlated with increased theta field power within the DMN. The degree of prefrontal theta power fluctuation between active and resting conditions was shown to positively correlate with somatic depression subtype scores. Increased alpha field power within the DMN at rest was observed to be significantly correlated with increased cognitive depression subtype score.
