Research Abstract

We conducted studies with an ultimate aim of elucidating neural computations for social decision making. While we made several achievements towards the aim, here we summarize the result of a most central study. Using human fMRI experiment, combined with so-called model-based analysis, we investigated brain functions for value-based decision making, comparing two situations ; when the subject makes value-based decisions for their self reward and when the subjects predicts what value-based decision another person would make, when the other person is in the same situation for themselves. We found that the ventromedial frontal cortex plays a central role in simulating the other's value-based decision making process.
