"Cortical Organization of Body Part Relationships"
In the past 30 years, human and monkey neuroimaging studies have extensively investigated category-selective regions of the visual cortex. While a great deal of work has been done on face-selective cortical areas, body-selective areas remain poorly understood. Given the importance of body stimuli in our daily lives, we sought to further investigate the processing dynamics of the neural mechanisms underlying body perception. Using 3 Tesla fMRI, we presented human subjects with apertures containing a hand and wrist that were presented normally or parametrically varied in rotation to induce the percept of an aligned arm or misaligned arm parts, respectively. We observed modulation of the activity in fusiform areas, but not extrastriate areas, as a function of subjects' perception. Furthermore, we observed activity in retinotopic regions that is consistent with predictive coding models of visual processing.
