EEG Default Mode Network in the Human Brain: Spectral Field Power, Coherence Topology, and Current Source Imaging

Default network in the human brain depicts the state of brain activity at resting eyes-closed condition without stimulation, rendered as basal energy distribution, originally measured in hemodynamic PET and later fMRI. Now, we extend it to EEG, this study defines the spatial characteristics of EEG spectral field powers, their respective coherence network and underlying current source density at eyes-closed/open condition, compared to those in emotional and cognitive activations. The study protocols serve basic brain function for evaluation of altered brain dysfunction in disease or illness.
