Outline of Final Research Achievements

In the present study, we have investigated neural mechanisms associated with preference formation for faces that are repeatedly presented in supraliminal or subliminal fashion, by combining functional magnetic resonance imaging (fMRI) and a technique called mere exposure paradigm. We found that the orbitofrontal cortex, ventral striatum, and early visual cortices are associated with supraliminal mere exposure effect, whereas the dorsomedial prefrontal cortex and anterior cingulate cortex are associated with subliminal mere exposure effect.
