Abstract: Theories about object conceptual representation have been advanced greatly in the past decades by neuropsychological evidence of semantic category-specific deficit following brain damage. We here review the most recent corroborating evidence from the brain-imaging paradigm on brain-damaged as well as healthy populations. The current evidence indicates that sensory-motor modalities and/or semantic categories are possible constraints on the organization of conceptual information. And these modality or category-specific semantic subsystems might have structural and functional connectivities to other cognitive components such as sensory, motor and theory of mind.
