| Abstract: | Visual perspective taking (VPT), particularly level 2 VPT (VPT2), which allows an individual to understand that the same object can be seen differently by others, is related to the theory of mind (ToM), because both functions require a decoupled representation from oneself. Although previous neuroimaging studies have shown that VPT2 and ToM activate the temporo-parietal junction (TPJ), it is unclear whether common neural substrates are involved in both functions. To clarify this point, we directly compared the TPJ activation patterns of individual participants performing VPT2 and ToM tasks using functional magnetic resonance imaging and within-subjects design. A whole-brain analysis revealed that VPT2 and ToM activated overlapping areas in the posterior part of the TPJ. In addition, we found that both the peak coordinates and activated regions for ToM were located significantly more anteriorly and dorsally within the bilateral TPJ than those measured during the VPT2 task. We further confirmed that these activated areas were spatially distinct from the nearby extrastriate body area (EBA), visual motion area (MT+), and the posterior superior temporal sulcus (pSTS) using independent localizer scans. Our findings revealed that VPT2 and ToM have gradient representations, indicating the functional heterogeneity of social cognition within the TPJ. |
