abstract = {Saccades shift the retina with high-speed motion. In order
to compensate for the sudden displacement, the visuomotor
system needs to combine saccade-related information and
visual metrics. Many neurons in oculomotor but also in
visual areas shift their receptive field shortly before the
execution of a saccade (Duhamel, Colby, $\&$ Goldberg, 1992;
Nakamura $\&$ Colby, 2002). These shifts supposedly enable
the binding of information from before and after the
saccade. It is a matter of current debate whether these
shifts are merely location based (i.e., involve remapping of
abstract spatial coordinates) or also comprise information
about visual features. We have recently presented fMRI
evidence for a feature-based remapping mechanism in visual
areas V3, V4, and VO (Zimmermann, Weidner, Abdollahi, $\&$
Fink, 2016). In particular, we found fMRI adaptation in
cortical regions representing a stimulus' retinotopic as
well as its spatiotopic position. Here, we asked whether
spatiotopic adaptation exists independently from retinotopic
adaptation and which type of information is behaviorally
more relevant after saccade execution. We first adapted at
the saccade target location only and found a spatiotopic
tilt aftereffect. Then, we simultaneously adapted both the
fixation and the saccade target location but with opposite
tilt orientations. As a result, adaptation from the fixation
location was carried retinotopically to the saccade target
position. The opposite tilt orientation at the retinotopic
location altered the effects induced by spatiotopic
adaptation. More precisely, it cancelled out spatiotopic
adaptation at the saccade target location. We conclude that
retinotopic and spatiotopic visual adaptation are
independent effects.},
