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

<p>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.</p>
