The hypothesis that an early adolescent brain growth plateau and spurt exists and that this plateau and spurt influence students' ability to reason scientifically and to learn theoretical science concepts was tested. In theory, maturation of the prefrontal lobes during early adolescence allows for i

Abstract
Changes in apparent ^31^P spinβlattice relaxation times (T~1~) associated with brain development were investigated in rat pups. While analysis of variance showed strong age dependency in [PME]/[ATP] and [PCr]/[ATP], the T~1~ values of PME, PCr, and ATP did not show any age dependency. The studies indicate that in contrast to the data which indicated agingβrelated changes in the T^1^ values of PME, the observed changes in PME during neonatal development are likely to be quantitative in nature.
