“…Based on previous reports of abnormal laterality of the ADHD brain (Dennis and Thompson, 2013;Shang et al, 2013;Cao et al, 2014;Hale et al, 2014Hale et al, , 2015Keune et al, 2015;Silk et al, 2015), we could postulate that the asymmetric expression of neurodevelopmental genes might be at the origin of structural and functional changes in this disorder. However, these changes are not clear yet, as both a dysfunctional activity of the right hemisphere (Vance et al, 2007;Smith et al, 2008;Chamberlain et al, 2009;Bush, 2011) and the opposite (Cao et al, 2014;Hale et al, 2014Hale et al, , 2015 have been reported in literature. Moreover, the reflections of these unilateral activation deficits on functional connectivity are not trivial and require dedicated analyses focused on network properties (Dennis and Thompson, 2013;Cao et al, 2014).…”
