“…Criticality has been claimed for explaining the brain since long ago (Bak, 1996), but it is in the last decade that a group of research articles have presented evidence of its presence and discussing its implications Fraiman et al, 2009;Haimovici et al, 2013;Hudetz et al, 2014;Marinazzo et al, 2014;Stramaglia, 2014;Tagliazucchi et al, 2012). However, criticality does not mean the same thing when studying the small-world properties of anatomical or functional (mathematically derived) networks (Bullmore & Sporns, 2009;Gafarov, 2016;Rubinov & Sporns, 2010;M.P. van den Heuvel, Stam, Boersma, & Hulshoff Pol, 2008), or the power-law distribution of functional data (Chialvo, 2004(Chialvo, , 2010Expert et al, 2011;Fraiman et al, 2009;Fraiman, Chialvo, & Breakspear, 2012;Sporns, Chialvo, Kaiser, & Hilgetag, 2004;Tagliazucchi et al, 2012), or the information transfer in an Ising model (Marinazzo et al, 2014) or when proposing non-linear functional dynamics on anatomically connected nodes (Haimovici et al, 2013).…”
