About
George R. Mangun is Distinguished Professor of Psychology and Neurology at the University of California, Davis. He was the founding director of the UC Davis Center for Mind and Brain, served as Chair of Psychology, and was Dean of Social Sciences in the College of Letters & Science from 2008-2015. He leads the NIH-supported Laboratory for the Neural Mechanisms of Attention, and serves as Director of the Kavli Summer Institute in Cognitive Neuroscience, supported by NIMH and NIDA. Professor Mangun consults on numerous university, U.S. government and international scientific panels and advisory boards, including for the National Institutes of Health, the National Academy of Sciences, the European Research Council and the Max Planck Society. He is coauthor of the textbook, Cognitive Neuroscience: The Biology of the Mind (W.W. Norton, 2019); now in its fifth edition, the book has been translated into French, Italian, Portuguese and Chinese. Among several other books and special journal issues, with Michael S. Gazzaniga, he is also the co-editor of the authoritative book, the The Cognitive Neurosciences (MIT Press, 2013). Professor Mangun is an associate editor of the Journal of Cognitive Neuroscience, and the Treasurer of the Cognitive Neuroscience Society.
Research Focus
Professor Mangun's work on the cognitive neuroscience of attention investigates how we perceive, attend, ignore and become aware of events in our environment. Recordings of event-related brain potentials (ERP) from healthy persons and special patient groups provide high temporal resolution measures of stimulus processing in the human brain. The goal of this research is to identify the mechanisms of attentional selection by permitting sensory analysis of attended and ignored stimuli to be studied under a wide variety of task circumstances. To identify the brain systems and circuits involved in various attentional processes (i.e., control and selection), tools such as functional magnetic resonance imaging (fMRI) are used in conjunction with ERPs. fMRI permits the living human brain to be revealed as it functions to enable our sensations, thoughts and actions. The information obtained from these combined behavioral, neuropsychological and neurophysiological studies yields insight into the computational and functional neuroanatomical structure of human cognition, and is essential for addressing the deficits in attention and awareness that accompany neurological and psychiatric disease.
