Scale-free modulation of resting-state neuronal oscillations reflects prolonged brain maturation in humans

Human neuronal circuits undergo life-long functional reorganization with profound effects on cognition and behavior. Well documented prolonged development of anatomical brain structures includes white and gray matter changes that continue into the third decade of life. We investigated resting-state EEG oscillations in 1433 subjects from 5 to 71 years. Neuronal oscillations exhibit scale-free amplitude modulation as reflected in power-law decay of autocorrelations-also known as long-range temporal correlations (LRTC)-which was assessed by detrended fluctuation analysis. We observed pronounced i... Mehr ...
