Maturational Patterns of Sigma Frequency Power Across Childhood and Adolescence: A Longitudinal Study

Conclusions:We hypothesize that these maturational brain changes result from synaptic elimination which decreases sleep depth and streamlines circuits. SFP displays a maturational trajectory different from both delta and theta power. Theories on the function of sigma must be reconciled with its maturational trajectory. These findings further demonstrate the value of sleep EEG for studying noninvasively the complex developmental brain changes of adolescence.Citation:Campbell IG, Feinberg I.
