Functional organization of LG's visual cortex on flattened cortical maps. (A) Delineation of LG's visual system organization (see Gilaie-Dotan et al., 2009) displaying normal V1 and V5/MT+ response patterns (indicated by green contours), abnormal deactivations in intermediate visual regions (red contours). LG's dorsal stream appeared normal (dotted green). His ventral stream lateral occipital areas were activated above normal, but did not display the expected sensitivity to object stimuli (dotted red). (B) Functional connectivity of LG's right V5/MT+ (delineated in black contour) to the fronto-parietal nodes of the action perception system (APS) during viewing movie clips that included biological motion (see Section 6.1). Yellow to orange patches display regions that were significantly correlated with LG's right V5/MT+ activity while he was watching the video clips (r > = 0.377, pcorrected < = 0.0001). LG's V5/MT+ functional connectivity pattern to the APS resembles the one seen in the normal brain (e.g., Saygin et al., 2004), in contrast to his intermediate visual cortical areas (shaded in turquoise). (C) Structural images of LG's brain. No discernable cortical abnormality was detected (Gilaie-Dotan et al., 2009). IPS – intraparietal sulcus, PreCS – precentral sulcus, IFS – inferior frontal sulcus, STS – superior temporal sulcus, LS – lateral sulcus, CS – central sulcus, RH – right hemisphere, LH – left hemisphere, P – posterior, A – anterior, D – dorsal, V – ventral.
