Data for: Neural basis of social influence of observing other’s perception in dot-number estimation

This functional magnetic resonance imaging study reports the neural basis
of the social influence of observing others’ perceptions in dot-number
estimation. We found that the medial prefrontal cortex (MPFC) was
associated with the detection of the self-other discrepancy. The posterior
part of MPFC was especially functionally connected with the right superior
parietal lobule (SPL), which is sensitive to numerical perception. The SPL
activation was modulated after observing others’ perceptions in the
dot-number estimation task. Furthermore, the multivariate pattern analysis
showed that the spatial activity patterns altered after the observation.
These suggest that the MPFC detects the self-other discrepancy of
numerical perception and communicates with the number-sensitive SPL, and
triggers the modulation of the activation in the SPL.
