“…Concurrently, the field of criticality in neural systems has received extensive treatment, primarily via studies of cotemporal sequences of neural activity, otherwise known as “neural avalanches” (Beggs and Plenz, 2003 , 2004 ; Beggs and Timme, 2012 ). Many recent studies have produced evidence that suggests neural systems are poised at or near a critical point (Beggs and Plenz, 2003 ; Petermann et al, 2006 ; Mazzoni et al, 2007 ; Gireesh and Plenz, 2008 ; Pasquale et al, 2008 ; Hahn et al, 2010 ; Friedman et al, 2012 ; Priesemann et al, 2013 ; Lombardi et al, 2014 , 2016 ; Priesemann et al, 2014 ; Williams-Garcia et al, 2014 ; Shew et al, 2015 ). Furthermore, many studies (see Beggs, 2008 ; Chialvo, 2010 ; Beggs and Timme, 2012 for reviews) have found important implications for the brain if it is indeed operating at or near a critical point, such as optimal communication (Beggs and Plenz, 2003 ; Bertschinger and Natschlager, 2004 ; Ramo et al, 2007 ; Tanaka et al, 2009 ; Shew et al, 2011 ), information storage (Socolar and Kauffman, 2003 ; Kauffman et al, 2004 ; Haldeman and Beggs, 2005 ), computational power (Bertschinger and Natschlager, 2004 ), dynamic range (Kinouchi and Copelli, 2006 ; Shew et al, 2009 ), and phase sychrony (Yang et al, 2012 ).…”
