Key findings

  • Delta and theta power decreased with age; alpha2 and beta increased
  • Peak alpha frequency rose slightly
  • Males showed more alpha power, without a sex difference in peak frequency

A longitudinal study following children from age 10 through early adolescence to map how the EEG power spectrum matures. Slow-wave power fell and faster activity rose with age, largely driven by a rising peak alpha frequency.
