Abstract

How does the visual system maintain a stable perception of the world across saccadic eye movements that continuously shift the retinal image? We applied transcranial magnetic stimulation (TMS) over the posterior parietal cortex (PPC) in healthy adults during a visual stability task. TMS disrupted performance in a spatiotopic localization condition but not in a retinotopic condition, establishing a causal role for PPC in the trans-saccadic updating of spatial representations. These findings link PPC function to the neural mechanisms of visual stability.
