Zusammenfassung

The Müller-Lyer illusion is an optical illusion that alters the perceived length of a line via arrows attached to its end. Recent imaging studies revealed that ventral and dorsal stream areas contribute to the processing of the Müller-Lyer illusion (Weidner et al., 2010; Weidner & Fink, 2007). Here we investigated [using dynamic causal modeling (DCM; Friston, Harrison, & Penny, 2003)] the effects of this illusion on the effective connectivity of the brain areas involved in coding illusion strength. Strength of the Müller-Lyer illusion was parametrically modulated while participants performed either a landmark ta…
