Strategy use is common in our behavioral repertoire. A strategy can be defined as a set of computations associated with the act of planning and directing overall operations and movements involved in a task. A behavioral strategy that conscious behaving primates spontaneously adopted in order to maximize their rewards have been well characterized in the literature. These are called "Repeat-Stay"/"Change-Shift" strategy, and were shown to be associated with prefrontal neuronal activity during multi-unit intra-cortical recordings, clearly indicating a special role played by the prefrontal cortex in computing strategy use. It is important to understand how the human brain computes and processes strategies. This study aims at understanding the activation patterns, and neuronal connectivity in the human brain when engaged in tasks that require strategies. We hypothesize that application of strategies to solve tasks would show specifically and significantly increase Blood Oxygenation Dependant (BOLD) signal, particularly the fronto-polar cortex (PFp), ventral and orbitofrontal prefrontal cortex (PFV+o) in the human brains.
