2020, CortexCitation Excerpt :Note that this hyperactive engagement of processing in ipsilesional space is independent of any disengage deficits towards contralesional space, which was not measured in this study due to the targets and masks only appearing at the same spatial position or vertically displaced. Indeed, several studies have demonstrated an ipsilateral hyperorienting of attention after parietal lesions or disruption from TMS (Blankenburg et al., 2008; D’Erme et al., 1992; Hilgetag, Theoret, & Pascual-Leone, 2001; Seyal et al., 1995; Szczepanski & Kastner, 2013). Despite these compelling lines of evidence ipsilesional hyperorienting, however, the data from the current study suggest that some other mechanism may be at play because enhanced attention should have reduced the effectiveness of the subsequent metacontrast mask, as previous studies have shown (Boyer & Ro, 2007; Ramachandran & Cobb, 1995).
