- Critical brain dynamics, specifically near-critical dynamics in the alpha band and 1/f aperiodic exponent, are linked to higher intelligence in children.
- Higher IQ children exhibit functional excitation/inhibition (fE/I) ratios closer to the theoretical critical value of 1 in association cortices compared to lower IQ children.
- The relationship between critical dynamics and IQ varies across the cortical hierarchy, with stronger associations in higher-order association networks than in sensorimotor networks.
- Age moderates the relationship between fE/I and IQ, with the association-sensorimotor gradient most evident in adolescents.
- The study supports the hypothesis that developmental modulation of critical dynamics enhances cognitive processing efficiency.
