“…These connections further support our claim regarding the central involvement of sub-cortical regions such as the pulvinar nuclei in spatial attention bias. In line with our findings, neuro-imaging studies suggest that the pulvinar nucleus is related to serial search (Fairhall et al, 2009), covert shifts of attention (Nobre et al, 1997), and attentional selection (Snow et al, 2009). Moreover, lesion studies in humans showed the critical role of the pulvinar in engagement of attention (Rafal and Posner, 1987), spatial and temporal components of feature binding (Arend et al, 2008), and visual search (Ward and Arend, 2007).…”
