The human occipitotemporal cortex (OTC) contains a number of regions specialized for processing particular types of sensory stimuli: including the lateral occipital complex (LOC), an object-selective area; the fusiform face area (FFA), a face-selective area; the parahippocampal place area (PPA), a scene-selective area; and the extrastriate body area (EBA), a body part-selective area. This study examined resting-state connectivity patterns of functionally localized LOC, EBA, FFA and PPA. Results indicate that regions of OTC exhibit both common and differential connectivity patterns. The EBA exhibited preferential connectivity with the default mode network, while FFA exhibited increased connectivity with the frontoparietal attention network.
