A number of areas in the human occipitotemporal cortex are specialized for processing particular types of sensory stimuli. Among these areas are the lateral occipital complex (LOC), an object-selective area and the extrastriate body area (EBA), a body part-selective area. This study used seed-based and graph theory approaches to test whether these areas connect to distinct resting-state networks. LOC and EBA exhibited different functional connectivity patterns. LOC interacted more with motor regions and lateral frontoparietal regions involved in processing external stimuli. In contrast EBA interacted more with somatic sensorimotor regions and DMN regions involved in self-referential processing.
