“…While it is unclear how microstructural characteristics, indexed by and R1, in tracts linking pSTS body and ATL leads to less influence of body on facial expression perception, the location of these tracts lends support to previous findings in humans and monkeys pointing towards ATL as potential sites of face and body integration(Fisher & Freiwald, 2015; Harry et al, 2016; Teufel et al, 2019). Indeed, within the context of recent proposals put forward by Taubert et al (2021), our microstructural results provide some support for face and body networks being weakly integrated in early stages of processing, insofar as the link between tract microstructure from OFA to FFA and body posture perception indicates some processing of body posture within face pathways, with face and body processing becoming more integrated downstream of FFA, particularly leading to ATL.…”

Facial expression and body posture recognition have protracted developmental trajectories. Interactions between face and body perception, such as the influence of body posture on facial expression perception, also change with development. While the brain regions underpinning face and body processing are well-defined, little is known about how white-matter tracts linking these regions relate to perceptual development. Here, we obtained complementary diffusion magnetic resonance imaging (MRI) measures (fractional anisotropy FA, spherical mean Ṧμ), and a quantitative MRI myelin-proxy measure (R1), within white-matter tracts of face- and body-selective networks in children and adolescents and related these to perceptual development. In tracts linking occipital and fusiform face areas, facial expression perception was predicted by age-related microstructural development, as measured by Ṧμ and R1, as well as age-independent individual differences in microstructure, as measured by FA. Tract microstructure linking the body region in posterior superior temporal sulcus with anterior temporal lobe (ATL) was related to the influence of body on facial expression perception, supporting ATL as a site of face and body network convergence. Overall, our results highlight age-dependent and age-independent constraints that white-matter microstructure poses on perceptual abilities during development and the importance of complementary microstructural measures in linking brain structure and behaviour.

“…Thus, our observations here suggest that body stimuli are processed in a unique computational pipeline where the processing of expressions is ubiquitous. Although consistent with a large literature (9-12, 14, 24), the reasons why body expressions would be processed separately from facial expressions remain unknown and warrant further investigation (25).…”

Body language is a powerful tool that we use to communicate how we feel, but it is unclear whether other primates also communicate in this way. Here, we use functional magnetic resonance imaging to show that the body-selective patches in macaques are activated by affective body language. Unexpectedly, we found these regions to be tolerant of naturalistic variation in posture as well as species; the bodies of macaques, humans, and domestic cats all evoked a stronger response when they conveyed fear than when they conveyed no affect. Multivariate analyses confirmed that the neural representation of fear-related body expressions was species-invariant. Collectively, these findings demonstrate that, like humans, macaques have body-selective brain regions in the ventral visual pathway for processing affective body language. These data also indicate that representations of body stimuli in these regions are built on the basis of emergent properties, such as socio-affective meaning, and not just putative image properties.

“…Body perception operates at a much longer distance than face perception and provides information about emotions, intentions, and actions relevant for social interaction (de Gelder et al, 2010). Yet, aside from studies of the body as a perceptual object category, our understanding of whole-body perception is still very limited (de Gelder and Poyo Solanas, 2021; Taubert et al, 2022). Despite a vast literature on the perception of action and intention that in fact assumes that body perception is involved (Orban et al, 2021), recent theories about social perception and social brain networks do not yet integrate findings from body perception studies (Patel et al, 2019; Pitcher and Ungerleider, 2021).…”

This ultrahigh field 7T fMRI study addressed the question of whether there exists a core network of brain areas at the service of different aspects of body perception. Participants viewed naturalistic videos of monkey and human faces, bodies, and objects along with mosaic-scrambled videos for control of low-level features. ICA-based network analysis was conducted to find body and species modulations at both the voxel and the network levels. Among the body areas, the highest species selectivity was found in the middle frontal gyrus and amygdala. Two large-scale networks were highly selective to bodies, dominated by the lateral occipital cortex and right superior temporal sulcus (STS) respectively. The right STS network showed high species selectivity, and its significant human body-induced node connectivity was focused around the extrastriate body area (EBA), STS, temporoparietal junction (TPJ), premotor cortex, and inferior frontal gyrus (IFG). The human body-specific network discovered here may serve as a brain-wide internal model of the human body serving as an entry point for a variety of processes relying on body descriptions as part of their more specific categorization, action, or expression recognition functions.
