“…Hasson et al (2003) report that the activation for faces in their congenital prosopagnosia patient is normal with respect to the anatomical location, activation profiles and hemispheric laterality of the FFA in controls. On the other hand, two earlier studies by Marotta, Genovese and Behrmann (2001) and Hadjikhani and de Gelder (2002) report that the activation for faces in the fusiform gyrus in their patients with acquired and early prosopagnosia, respectively, is not normal compared to controls.…”

“…The cortical damage in one of Marotta et al (2001) patients was right anterior and posterior temporal while in the other the damage was to the right temporal and medial occipital lobes and the right fusiform gyrus. These patients, however, exhibited more functional activation for faces in the anterior portion of the fusiform gyrus than did controls and one patient showed more left than right hemisphere activation.…”

“…Yovel and Kanwisher (2004) showed that a region that responds more strongly to objects than to texture patterns (the lateral occipital complex; Malach et al, 1995) was also more responsive to a task that required the processing of parts of upright faces or houses than to a task that required the processing of configural information (i.e., spacing among the parts of the stimulus) of the same stimuli. Marotta, Genovese, and Behrmann (2001) showed that faces activated more posterior regions of the fusiform gyrus in prosopagnosics than in normal adults. Marotta et al speculated that the prosopagnosics were recruiting posterior regions for feature-based face recognition, which is less efficient than relational processing and may underlie their face recognition deficit.…”

We explored developmental changes in neural substrates for face processing, using fMRI. Children and adults performed a perceptual-matching task with upright and inverted face and animal stimuli. Behaviorally, inversion disrupted face processing more than animal processing for adults and older children. In line with this behavioral pattern, the left middle occipital gyrus showed a stronger face than animal inversion effect in adults. Moreover, a superior aspect of this region showed a greater face inversion effect in older than in younger children, indicating a developmental change in the processing of inverted faces. The visual regions recruited for inverted face processing in adults also overlapped more with brain regions involved in the viewing of upright objects than with regions involved in the viewing of upright faces in an independent localizer task. Hence, when faces are inverted, adults recruit regions normally engaged for recognizing objects, possibly pointing to a role for the featural processing of inverted faces.

“…Following a lesion sustained in adulthood (except for CR, who was aged 16 y), all individuals reported visual perceptual problems and have well-established form-processing deficits. Table 1 summarizes the key demographics, neuropsychological descriptions, and detailed visual performance (including visual motion perception) of each patient; further details are available in Supporting Information and in earlier publications [SM (61,(64)(65)(66)(67)(68)(69)(70), CR (61,(65)(66)(67)70), EL (61,(70)(71)(72)(73)(74)(75), GB (61,75), SH (70,75), and EC (61)].

Identifying the movements of those around us is fundamental for many daily activities, such as recognizing actions, detecting predators, and interacting with others socially. A key question concerns the neurobiological substrates underlying biological motion perception. Although the ventral "form" visual cortex is standardly activated by biologically moving stimuli, whether these activations are functionally critical for biological motion perception or are epiphenomenal remains unknown. To address this question, we examined whether focal damage to regions of the ventral visual cortex, resulting in significant deficits in form perception, adversely affects biological motion perception. Six patients with damage to the ventral cortex were tested with sensitive point-light display paradigms. All patients were able to recognize unmasked point-light displays and their perceptual thresholds were not significantly different from those of three different control groups, one of which comprised brain-damaged patients with spared ventral cortex (n > 50). Importantly, these six patients performed significantly better than patients with damage to regions critical for biological motion perception. To assess the necessary contribution of different regions in the ventral pathway to biological motion perception, we complement the behavioral findings with a fine-grained comparison between the lesion location and extent, and the cortical regions standardly implicated in biological motion processing. This analysis revealed that the ventral aspects of the form pathway (e.g., fusiform regions, ventral extrastriate body area) are not critical for biological motion perception. We hypothesize that the role of these ventral regions is to provide enhanced multiview/posture representations of the moving person rather than to represent biological motion perception per se.
