Converging lines of evidence point to the occipitotemporal cortex (OTC) as a critical structure in visual perception. For instance, human functional magnetic resonance imaging (fMRI) has revealed a modular organisation of object-, face-, body- and scene-selective visual areas in OTC and disruptions to the processing within these regions, either in neuropsychological patients or through transcranial magnetic stimulation (TMS), can produce category-specific deficits in visual recognition. In the present paper, Gallivan and colleagues show, using fMRI and pattern classification methods, that the activity in several areas of the OTC also represent how stimuli will be interacted with by the body – a level of processing more traditionally associated with the preparatory activity in sensorimotor circuits of the brain.
