Two specialized systems for body perception. A, For each stimulated area, we computed inverted/upright postures accuracy ratios as indicators of body inversion effect. To test the effect of specific cortical virtual lesions on the body inversion effect, inversion ratios after stimulation of EBA, SPL, and vPMc were normalized to the ratio after control stimulation of V1. The normalized body inversion effect ratio was significantly higher after interfering stimulation of right EBA than of right SPL and left vPMc. Error bars indicate SEM. *p < 0.05. B, Body postures seem to be processed by two partially independent cortical systems: the configural system analyzes body configurations, whereas a local system analyzes body-part details and form features. The present study suggests that configural processing may rely on sensorimotor regions, whereas local processing may rely on visual areas.
