Heteroscedasticity of annualized percent changes in functional brain development. Functional measures of brain changes are represented in rows, while developmental variables (i.e., age, sex, puberty) are represented in columns. Brighter hues indicate greater heteroscedasticity of functional brain change with respect to A) age (9.0 -− 9.39; 9.4 -− 9.99; 10.0 -− 10.49; 10.5 -− 10.99 years), B) sex (male, female), and C) pubertal stage (prepubertal, early puberty, mid-pubertal) at the time of study enrollment (i.e., larger differences in variance between levels). Abbreviations: FC = functional connectivity; L = left; R = right; BOLD = blood-oxygen-level-dependent; F-K = Fligner-Killeen.
