“…The strong correlation of interhemispheric connectivity was absent in a minimally conscious patient who had a brainstem lesion (Salvador et al, 2005 ). Also, subjects with various disease states such as Parkinson's disease (Spagnolo et al, 2013 ; Hohlefeld et al, 2014 ; Luo et al, 2015 ), epilepsy (Thordstein and Constantinescu, 2012 ; Liu et al, 2013 ; Lin et al, 2014 ; Yadollahpour et al, 2014 ; VanHaerents et al, 2015 ), stroke (Buchkremer-Ratzmann et al, 1996 ; Liepert et al, 2000 ; Takatsuru et al, 2009 ; Lim et al, 2014 ; Liu et al, 2015 ), and peripheral nerve injury (Pelled et al, 2007b , 2009 ; Pawela et al, 2010 ; Li et al, 2011 ; Han et al, 2013 ) showed alteration of interhemispheric interaction. Understanding the process of the disruption of interhemispheric interaction in brain injury and neurodegenerative disease may give important clues in optimizing rehabilitation and recovery from disease states.…”
