The pattern described for Rodolfo's cortex—initially thin, thickening, and then thinning again around the age of 12 or 13—is consistent with findings related to high intelligence. Research has shown that a thicker cortex that later thins is associated with higher intelligence, as the thinning process is thought to reflect synaptic pruning, where the brain refines its neural connections to become more efficient.
