How the human mind emerges from the brainactivity is one of the most challenging problems　in scientific research. Our researches are focusing on brain mechanisms of cognition and memory in humans. We are also interested in brain mechanisms underlying social behaviors. Our main research tool is functional magnetic resonance imaging (fMRI), which enables us to scan human brain activity.
