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.
