It reviews the evidence that the lateral PFC (lPFC) plays an important role in flexible cognitive control, and the evidence for highly dynamic representations in lPFC. The chapter considers how these representations can be used to establish task-relevant networks throughout the brain. Neurophysiological studies of the lPFC demonstrate that neurons have a set of properties that may make them uniquely well suited to acting as a cognitive controller. First, individual neurons in the lPFC are known to represent the contents of working memory (WM). WM provides a temporary but stable platform for flexible, context-dependent processing. Early neurophysiological recordings in the lPFC suggested that task-relevant information is maintained via persistent delay activity. The essential point is that task-relevant input changes the effective connectivity of the network to construct a temporary task-dependent circuit for WM-guided behaviour.
