Neuroscience of Rule-Guided Behavior

Katsuyuki Sakai

Oxford University Press

This chapter shows that part of the anterior frontal cortex, the frontopolar cortex (FPC), is involved in the preparation of behaviors that require active manipulation of external information. During task preparation, the FPC interacts with different posterior prefrontal regions, depending on the task at hand. Further, the prefrontal activity that reflects behavioral rules (i.e., the task set) also predicts subsequent performance of cognitive tasks, as well as the level of activity of posterior areas during task performance. Based on these findings, this chapter argues that the interactions between the FPC and posterior frontal regions reflect not only the maintenance of the rule of the task to be performed, but also the process of implementing the rule for subsequent behavior.

Keywords:   anterior prefrontal cortex, task preparation, task set, rule maintenance
