Even the simplest decision-making problems require predicting future events in an environment that is constantly changing. Making a choice requires a commitment to the statistical process underlying environmental change, determining the cost and benefit of searching for more information, and accepting the risk of making the wrong choice. Because of these difficulties, the brain hedges its bets as it follows a divide-and-conquer strategy, and distinct networks of brain areas support different decision strategies.

To investigate the details of these mechanisms, we develop computational models that implement decision processes, and predict human behavior under uncertainty. By taking internal variables from these models we generate hypothetical time-series that describe how the computations underlying a decision process would be implemented in the brain. We then use machine learning techniques to identify brain regions exhibiting activation profiles suggestive of a role for those areas in implementing a specific computational process.
