However, information that does not reach that level cannot and should not be fully excluded from ever reaching it because the information may have behavioral relevance. A critical challenge that it must address is to ensure that only goal-relevant information reaches the level of focused attention. The brain is constantly bombarded with more information from multiple sensory channels than it can process. This hypothesis and theory article justifies the validity and properties of such an account and relates experimental findings to the frontoparietal network under the framework of information theory. This account treats the brain as an information-processing entity where cognitive control and its underlying brain networks play a pivotal role in dealing with conditions of uncertainty. A novel and comprehensive account of cognitive control is proposed using concepts from information theory, which is concerned with communication system analysis and the quantification of information. Despite a considerable focus in the literature on the cognitive control of information processing, neural mechanisms underlying control are still unclear, and have not been characterized by considering the quantity of information to be processed. Our ability to efficiently process information and generate appropriate responses depends on the processes collectively called cognitive control. 2Departments of Psychiatry and Neuroscience, Icahn School of Medicine at Mount Sinai, New York, NY, USA.1Department of Psychology, Queens College, The City University of New York, Flushing, NY, USA. ![]()
