Activation results for the conventional univariate analyses. A, During the imagery task, comparisons against baseline confirmed relative increases in activity distributed throughout visual cortex, including cuneus (Cu), lingual gyrus (LiG) and middle temporal gyrus (MTG). Event-related increases were also observed within superior temporal sulcus/Heschl's gyrus (STG/HG). B, During the perceptual task, a similar network of brain areas was also activated, with peaks in inferior occipital gyrus (IOG), middle occipital gyrus (MOG), middle temporal gyrus (MTG) and fusiform gyrus (FG). Beyond visual cortex, precentral gyrus (PrG) was also active during the perceptual task. All activation maps are corrected for multiple comparisons (pFDR < 0.05). Shaded brain areas were beyond the functional data acquisition field of view within at least one subject, and therefore not included in the group analyses. The calcarine sulcus (CcS) is indicated by the black line superimposed over coronal slices.
