Key points

  • The original attention framework has successfully integrated multiple research disciplines.
  • New brain networks have been identified for orienting and executive attention functions.
  • Developmental studies reveal significant changes in attention control systems from infancy to childhood.
  • Specific genetic variations, interacting with experience, explain some individual differences in attention.

Abstract

Here, we update our 1990 Annual Review of Neuroscience article, "The Attention System of the Human Brain." The framework presented in the original article has helped to integrate behavioral, systems, cellular, and molecular approaches to common problems in attention research. Our framework has been both elaborated and expanded in subsequent years. Research on orienting and executive functions has supported the addition of new networks of brain regions. Developmental studies have shown important changes in control systems between infancy and childhood. In some cases, evidence has supported the role of specific genetic variations, often in conjunction with experience, that account for some of the individual differences in the efficiency of attentional networks. The findings have led to increased understanding of aspects of pathology and to some new interventions.
