Average power density spectra for derivations C3LM and O1LM. Power density spectra averaged across participants of waking EEG were calculated for derivations C3LM (left) and O1LM (right) for three recording sessions separated by a week. Eyes open (EO) conditions are shown with blue, red, and green lines and eyes closed (EC) are shown in cyan, black, and magenta. Note that power density is plotted on a logarithmic scale and the scales are different for the two derivations.
