ABSTRACT
Adolescent changes in human brain function are not entirely understood. Here, we used multiecho functional MRI (fMRI) to measure developmental change connectivity (FC) of resting-state oscillations between pairs 330 cortical regions and 16 subcortical 298 healthy adolescents scanned 520 times. Participants were aged 14 26 y on 1 3 occasions at least 6 mo apart. We found 2 distinct modes age-related FC: “conservative” “disruptive.” Conservative development was characteristic primary cortex, which strongly connected became even more the period from y. Disruptive association cortex regions, where remodeled: connections that weak stronger during adolescence, strong weaker. These quantified using maturational index (MI), estimated as Spearman’s correlation edgewise baseline FC (at y, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mi>F</mml:mi> <mml:msub> <mml:mrow> <mml:mi>C</mml:mi> </mml:mrow> <mml:mn>14</mml:mn> </mml:msub> </mml:math> ) adolescent ( <mml:mi mathvariant="normal">Δ</mml:mi> <mml:mo>−</mml:mo> <mml:mn>26</mml:mn> ), each region. systems (with negative MI) activated by social cognition autobiographical memory tasks prior fMRI data significantly colocated with maps aerobic glycolysis (AG), AG-related gene expression, postnatal surface expansion, shrinkage thickness.
