“…These results suggest that short-term adaptation duration leads to a position-invariant FAE, which is related to the reduction of the N170 ERP component. Consequently, the observed FAE is probably owing to the adaptation of the neurons responsible for the configural/holistic stages of face processing (for summary see [36,37]), rather than earlier processing steps.…”

It has been shown that prolonged exposure to a human face leads to shape-selective visual aftereffects. It seems that these face-specific aftereffects (FAEs) have multiple components, related to the adaptation of earlier and higher level processing of visual stimuli. The largest magnitude of FAE, using long-term adaptation periods, is usually observed at the retinotopic position of the preceding adaptor stimulus. However, FAE is also detected, to a smaller degree, at other retinal positions in a spatially invariant way and this component depends less on the adaptation duration. Several lines of evidences suggest that while the position-specific FAE involves lower level areas of the ventral processing stream, the position-invariant FAE depends on the activation of higher level face-processing areas and the fusiform gyrus in particular. In the present paper, we summarize the available behavioural, electrophysiological and neuroimaging results regarding the spatial selectivity of FAE and discuss their implications for the visual stability of object representations across saccadic eye movements.

“…Repetitive transcranial magnetic stimulation (rTMS) and neuroimaging studies have established that a specialized brain network involving the occipital and temporal cortices subserves perception of bodies in humans (Urgesi, Candidi et al, 2007;Urgesi, CalvoMerino et al, 2007;de Gelder et al, 2010;Minnebusch & Daum, 2009;Peelen & Downing, 2007). In particular, extrastriate body area (EBA) located at the posterior inferior temporal sulcus/middle temporal gyrus (Downing et al, 2001) and the fusiform body area located at the ventro-medial temporal cortex (Peelen & Downing, 2007) display a highly selective activity for visual presentations of human bodies.…”

Abstract:Although previous studies have suggested a certain degree of right hemisphere dominance for the response of extrastriate body area (EBA) during body perception, recent evidence suggests that this functional lateralization may differ between men and women. It is unknown, however, whether and how gender differences in body perception affect appreciating the beauty of the body conspecifics. Here, we applied five 10-Hz repetitive transcranial magnetic stimulation (rTMS) pulses over left and right EBA and over the vertex to investigate the contribution of visual body representations in the two hemispheres on esthetic body perception. Female and male healthy volunteers were requested to judge how much they liked opposite-and same-gender virtual model bodies or to judge their weight, thus allowing us to compare the effects of right-and left-EBA rTMS on esthetic (liking) and perceptual (weight) judgments of human bodies. The analysis of the esthetic judgments provided by women revealed that right-EBA rTMS increased the liking judgments of opposite-vs. same-gender models, as compared to both vertex and left EBA stimulation.Conversely, in men the liking judgments of opposite-gender models decreased after virtual disruption of both right and left EBA as compared to vertex stimulation. Crucially, no significant effect was found for the perceptual task, showing that left-and right-EBA rTMS did not affect weight perception. Our results provide evidence of gender difference in the hemispheric asymmetry of EBA in the esthetic processing of human bodies, with women showing stronger right hemisphere dominance in comparison with men.

“…Moreover, most research has defined and investigated the 1PP in terms of visual or visuospatial properties, whereas less attention has been given to the multisensory properties of the subjective 1PP, defined as the subjective experience of being directed at the world (Blanke and Metzinger 2009;Metzinger 2003;Ionta et al 2011;Blanke 2012;Pfeiffer et al 2013). The former 'perspective' has been defined and investigated as the visuospatial viewpoint of a given visual scene as seen by the participant and thus as centered on the participant's physical body (egocentric viewpoint).…”

Visuospatial viewpoint manipulation during full-body illusion modulates subjective first-person perspective

viewpoint had no effect on self-identification, but depended on the viewed object and visuotactile synchrony. Selflocation depended on visuospatial viewpoint (first experiment) and visuotactile synchrony (second experiment). Our results show that the visuospatial viewpoint from which the virtual body is seen during FBIs modulates the subjective 1PP and that such viewpoint manipulations contribute to spatial aspects of BSC. We compare the present data with recent data revealing vestibular contributions to the subjective 1PP and discuss the multisensory nature of BSC and the subjective 1PP.
