Distributed network flows generate localized category selectivity in human visual cortex
Fig 9
Other regions associated with visual category responses in the literature do not drive the fully-distributed model results.
(A) While our procedure for identifying functional complexes from the literature was systematic (see Methods), it was possible that excluded, category-responsive regions were driving the results in Figs 5–8. Such regions were excluded from functional complexes because they were either: (1) not supported by 10 or more peer-reviewed studies at the time of preparing this manuscript, (2) studies used experimental stimuli too distinct from the n-back visual categories, or (3) studies did not provide spatial information systematically consistent with standard volumetric and/or surface-based topography. These regions, held-out from source sets in this control analysis, were as follows (from left to right in panel A): the dorsal visuomotor stream for body selectivity; the occipital face area (OFA), inferior frontal gyrus (IFG), and orbitofrontal cortex (OFC) for face selectivity; the transverse occipital sulcus (TOS) for place selectivity; the intraparietal sulcus (IPS) and middle frontal gyrus (MF) for tool selectivity. Colors of regions are consistent with the functional network assignment used throughout all other figures. (B) For each body, face, place, and tool (left to right) selectivity analysis, individual participant’s (dots) visual selectivity scores were maintained between the results in Figs 5–8 (x-axes) and the same analyses with the regions in panel A held-out from the source set. This suggests that other category responsive regions in the literature did not drive the fully-distributed model findings.
