Recent neuroscience research is beginning to discover the brain regions involved in
decision-making under uncertainty, but little is known about whether or how these regions
functionally interact with each other. Here, we used event-related functional magnetic
resonance imaging to examine both changes in overall activity and changes in functional
connectivity during risk-taking. Results showed that choosing high-risk over low-risk
decisions was associated with increased activity in both anterior cingulate and orbitofrontal …
