abstract = {How the brain represents visual space is an unsolved
mystery. Spatial localization becomes particularly
challenging when visual information processing is briefly
disrupted, as in the case of saccadic eye movements, blinks,
or visual masks. As we have recently reported, a compression
of visual space, illustrated by displacements of shortly
flashed stimuli, can be observed in the temporal vicinity of
masking stimuli during ocular fixation (Zimmermann et al.,
2013). We here aimed at investigating the neural mechanisms
underlying these displacements using functional magnetic
resonance imaging. On the behavioral level, we detected
significant stimulus displacement when visual masks were
simultaneously presented. At the neural level, we observed
decreased human motion complex V5/MT+ activation associated
with these displacements: When comparing trials with a
perceived stimulus shift in space to trials of veridical
perception of stimulus localization, human V5/MT+ was
significantly less activated although no differences in
perceived motion can account for this. Data suggest an
important role of human V5/MT+ in the process of spatial
localization of briefly presented objects and thus extend
current concepts of the functions of human V5/MT+.},
