abstract = {The human visual system converts identically sized retinal
stimuli into different-sized perceptions. For instance, the
Müller-Lyer illusion alters the perceived length of a line
via arrows attached to its end. The strength of this
illusion can be expressed as the difference between physical
and perceived line length. Accordingly, illusion strength
reflects how strong a representation is transformed along
its way from a retinal image up to a conscious percept. In
this study, we investigated changes of effective
connectivity between brain areas supporting these
transformation processes to further elucidate the neural
underpinnings of optical illusions. The strength of the
Müller-Lyer illusion was parametrically modulated while
participants performed either a spatial or a luminance task.
Lateral occipital cortex and right superior parietal cortex
were found to be associated with illusion strength. Dynamic
causal modeling was employed to investigate putative
interactions between ventral and dorsal visual streams.
Bayesian model selection indicated that a model that
involved bidirectional connections between dorsal and
ventral stream areas most accurately accounted for the
underlying network dynamics. Connections within this network
were partially modulated by illusion strength. The data
further suggest that the two areas subserve differential
roles: Whereas lateral occipital cortex seems to be directly
related to size transformation processes, activation in
right superior parietal cortex may reflect subsequent levels
of processing, including task-related supervisory functions.
Furthermore, the data demonstrate that the observer's
top-down settings modulate the interactions between lateral
occipital and superior parietal regions and thereby
influence the effect of illusion strength.},
