Gyrification medição (dobradura cortical) em qualquer idade representa uma janela para o desenvolvimento do cérebro no início. Por isso, nós já desenvolveu um algoritmo para medir gyrification local em milhares de pontos sobre o hemisfério<sup> 1</sup>. Neste artigo, detalhamos o cálculo deste índice gyrification local.
