ANOVA tests on Characteristic Path Length features of Migraine with Aura versus Migraine Without Aura. The first column shows the Student t-test on the “lambda” and “diameter” factors (which stem for the medium path length and its distribution) in basal condition and during 0.5 cpd and 2 cpd spatial frequency visual stimulation. The lambda is clearly smaller for MA, as one can argue observing the “eccentricity” (distribution of the minima, right column) at all the stimulations and for all cortical bands (alpha band is here represented). The red horizontal line stems for the t-test confidence level (Bonferroni corrected) under which the probability of having distinct population is relevant
