Participants' brains were studied by functional magnetic resonance imaging signals after they had learned a decision-making task. During a subsequent resting phase, the replay of activity patterns in the hippocampus reflected the order of previous task-state sequences at a higher speed. Thus, sequential hippocampal reactivation might participate in human decision-making. The results support the importance of sequential reactivation in the human hippocampus for nonspatial decision-making and establish the feasibility of investigating such rapid signals with fMRI (functional magnetic resonance imaging), despite substantial limitations in temporal resolution. To date, a non-invasive, human-based method to measure fast brain activities was lacking. By combining this MRI technique with an algorithm for the detection of activity pattern, a method was developed for studying human brain processes.
