  • Abstract
  • Look Inside

It has been known that the prefrontal cortex participates in higher order behavioral controls, such as selecting an appropriate behavior, programming to perform a complex and purposeful behavior, and inhibiting inappropriate and unnecessary behaviors. Recent neurophysiological studies using non-human primates provide some clues to understand how the prefrontal cortex performs these behavioral controls. In the lateral prefrontal cortex, several kinds of neural activities related to behavioral controls have been observed. For example, some neurons exhibit delay-period activity which maintains information for generating forthcoming behavioral responses based on the cue stimulus presented before. Some neurons show neural activity representing what type of behavior is needed to perform and how this behavior is performed. Some neural activity represents the inhibition of motor responses. And, some neurons participate in the mechanism for generating appropriate behaviors based on a previously learned rule. In this review, we describe how the prefrontal cortex, especially the lateral prefrontal cortex, participates in behavioral controls by referring recent findings.
