“…We were able to replicate previous findings of the direct influence of a low arousal level induced by sleep deprivation on visuospatial attention (Fimm et al, 2006), and we were able to show that the smaller but neglect-resembling effect appears in extrapersonal space. These findings are relevant for the rehabilitation of neglect or attentional asymmetries in 3D space (Butler et al, 2004;Halligan & Marshall, 1991;Mennemeier et al, 1992;Robertson et al, 1998;Shelton et al, 1990;Thimm et al, 2006;Vuilleumier et al, 1998). Furthermore, the functional interdependence of the two attentional networks might be relevant to Attention Deficit Disorders as well, because various studies (Dobler et al, 2003Manly et al, 2005;Nigg et al, 1997;Sheppard et al, 1999;Voeller & Heilman, 1988) describe neglect symptoms or visual space biases in children with Attention Deficit Hyperactivity Disorder; potential therapeutic approaches might account for the functional overlap of alertness and visuospatial attention.…”
