“…Subjects also reported that they made no use of the eye region for tactile recognition. These subjective reports and the imaging results suggest that during tactile recognition of faces, subjects processed the faces more like other objects than like holistic face configurations (14). Even within the visual modality, face inversion impedes configural face processing (15) and results in increased activity in extrastriate cortical regions that respond more to nonface objects than to faces (16).…”

We investigated whether the topographically organized, categoryrelated patterns of neural response in the ventral visual pathway are a representation of sensory images or a more abstract representation of object form that is not dependent on sensory modality. We used functional MRI to measure patterns of response evoked during visual and tactile recognition of faces and manmade objects in sighted subjects and during tactile recognition in blind subjects. Results showed that visual and tactile recognition evoked category-related patterns of response in a ventral extrastriate visual area in the inferior temporal gyrus that were correlated across modality for manmade objects. Blind subjects also demonstrated category-related patterns of response in this ''visual'' area, and in more ventral cortical regions in the fusiform gyrus, indicating that these patterns are not due to visual imagery and, furthermore, that visual experience is not necessary for category-related representations to develop in these cortices. These results demonstrate that the representation of objects in the ventral visual pathway is not simply a representation of visual images but, rather, is a representation of more abstract features of object form.haptic perception ͉ fMRI ͉ supramodal cortex

“…Recent studies have shown that human body parts, such as faces (Kilgour & Lederman, 2002, 2006, hands, and feet (Kitada et al, 2009(Kitada et al, , 2010, and the facial expression of emotion (Lederman et al, 2007) can also be identified haptically.…”

“…Few studies have examined the haptic exploration of stimuli that represent body parts (Kilgour & Lederman 2002, 2006Kitada, Johnsrude, Kochiyama, & Lederman, 2009;Kitada, Dijkerman, Soo, & Lederman, 2010). Additionally, none of these studies investigated specifically motor simulation evoked by the handedness recognition task, but rather the dynamics of the haptic identification of body parts.…”

The handedness recognition of visually perceived body parts engages motor representations that are constrained by the same biomechanical factors that limit the execution of real movements. In the present study, we used small plastic cutouts that represented the human hand to investigate the properties of mental images generated during their haptic exploration. Our working hypothesis was that any handedness recognition task that involves body parts depends on motor imagery. Forty-four blindfolded, right-handed volunteers participated in a handedness evaluation experiment using their index finger to explore either the back or palm view of a haptic stimulus that represented the human hand. The stimuli were presented in four different orientations, and we measured the subjects' response times. Our results showed that stimulus configurations that resemble awkward positions of the human hand are associated with longer response times (p < .006), indicating that the haptic exploration of stimuli that represent body parts also leads to motor imagery that is constrained by biomechanical factors.

“…For example, Gobbini (2000, 2002) proposed that face recognition was represented in the brain as a distributed network of areas, but structured on a distinct core system centred around activity in the fusiform gyrus (Kanwisher, McDermott, & Chun, 1997;Sergent, Ohta, & MacDonald, 1992) as well as the occipital face area (e.g., Pitcher, Walsh, & Duchaine, 2011), to represent the invariant aspects of faces for identification. These areas are considered unimodal and predominantly visual (Casey & Newell, 2007;Kilgour & Lederman, 2002). Such a core system also incorporates a more anterior region of the brain, the superior temporal sulcus (e.g., Perrett et al, 1985), which represents the more changeable aspects of faces (e.g., lip movements in speech, facial expressions, eye gaze, etc.)…”
