Unmasking the contribution of low-level features to the guidance of attention

► Impairment of top-down control unmasks bottom-up guidance of overt attention. ► Neglect subjects exhibit a right spatial bias during free-viewing of natural scenes. ► Neglect subjects fixate low-level salient location in the neglected hemifield. ► Unilateral parietal rTMS reproduces neglect patients spatial bias behavior. ► Bilateral parietal rTMS reproduce neglect patient's guidance by low-level features.
