In this study, the correlations between precuneus activations and the switch cost in different switching situations also support this conclusion.
Neural activation analysis revealed that the magnitude of DLPFC, inferior parietal cortex, STS, insula and precuneus activation differentiated care and justice cognitions.
Lower bilateral striatum activation and left precuneus activation were found in LOSS than in CONTROL.
By contrast, we showed here that the precuneus activation, the vMPFC deactivation, and the enhanced functional connectivity between the two brain areas characterize the unique neurocognitive processes involved in the inference of HI.
These findings correspond to the study by Sommer et al. [14], who also found precuneus activation in both false and true belief reasoning about object location.
ADHD patients have been shown to have abnormal medial frontal and precuneus activation during reward reversal tasks (Finger et al. 2008).
The difference in precuneus activation linked to PT task between HI and AI was verified by two-sample t-tests comparing contrast values of signal intensity in the region of interest (ROI), a sphere with a 6 mm diameter centered at the peak voxel of the precuneus activation (t = 2.285, p = 0.03).
Precuneus activation was also observed in all contrasts of cooperation, deception, and cooperation/deception compared with the other conditions.
However, in a PET study by Ruby and Decety [16], there was more bilateral precuneus activation when taking a third person perspective than first person perspective.
The Precuneus activation detected in all comparisons is supposed to relate to mental imagery, self-processing operations and experience of agency [13], [56], [57].
