Cortical inflation study.

(a) A cortical surface taken from the NKI dataset²⁸; (b,c) inflated versions of this structure: an ‘intermediate’, with folding still evident and a ‘very inflated’ structure with no folds. (d–f) The evolution of the mean fraction of activated nodes (solid lines), together with a confidence interval of width 2σ (dotted lines) and the spread of activation fractions p in each realisation (shaded area). (g–i) Histograms showing the distribution of the times to full network activation, t*, obtained from 20,000 simulations in each network.
