| In our study the effects of aging were investigated on the resting EEG (eyes closed, eyes open conditions) in young (N=31, MA=22.71±3.58 yrs) and elderly (N=33, MA=66.09±3.88 yrs) adults. Absolute spectra, Omega complexity and synchronization likelihood were calculated in the conventional EEG frequency bands. No group differences were found regarding the frequency spectra. The total power was higher in the young in eyes closed condition, but eyes opening eliminated group differences. Omega complexity and synchronization likelihood showed group differences at anterior sites during eyes open condition: Omega complexity was higher and synchronization likelihood was lower in the elderly. Our results indicate in accord with the anatomical data that the frontal areas are the most sensitive to the effect of aging, which can be shown best with complexity measures in the resting EEG. |
