abstract = {In an event-related fMRI study, we investigated the neural
correlates of visual dimension and response changes. We used
a compound task, which required target selection by a
singleton feature, a unique color or motion direction,
before the appropriate motor response, which was determined
by target orientation, could be selected. Both types of
change elicited distinct patterns of activation, with
dimension-change-related activation primarily in posterior
visual areas and response-related activation primarily in
motor-related areas of the parietal and frontal cortices.
Response-change-related activation was delayed by about 1 s
relative to dimension-change-related activation, suggesting
that the latter is elicited by perceptual processes, whereas
the former reflects response-related or post-response
processes. Although dimension changes and response changes
rely on different processes, they are not independent:
response facilitation was observed for combined dimension
and response repetitions, this facilitation, however, was
disrupted by dimension changes.},
