From Wikipedia, the free encyclopedia

Geraint Rees (born November 27, 1967, United Kingdom - ) is a professor of cognitive neurology at the Institute of Cognitive Neuroscience and Institute of Neurology , University College London.

After medical training in Cambridge, Oxford and London, he completed his PhD under the supervision of Chris Frith at the University College London Functional Imaging Laboratory in 1999. He then worked as a postdoctoral fellow in Christof Koch's laboratory at the California Institute of Technology for two years before returning to the Institute of Cognitive Neuroscience at University College London in 2001. In 2002 he became a group leader with the award of a Senior Fellowship from the Wellcome Trust. In 2003 he was awarded the Young Investigator Medal of The Organization for Human Brain Mapping and in 2007 he will be awarded the Experimental Psychology Society Prize. His H-index is 24.

His work focuses on the neural mechanisms underlying human consciousness in health and disease. At present most work focuses on the neural correlates of particular types of conscious content, aiming to distinguish between conscious and unconscious representations in the human brain. As a considerable amount is already known about the anatomy and physiology of the visual system, much of the research in the laboratory focuses on visual awareness. However, his laboratory also studies the auditory and somatosensory systems. Most research involves functional MRI at high field, in combination with behavioral studies, transcranial magnetic stimulation and EEG/MEG. Previous work by Rees has suggested that subjective awareness of objects in the visual environment is associated not just with enhanced activation in visual areas of the occipital lobe, but also areas of parietal and prefrontal cortex often associated with attention. A major focus of this work is therefore in studying interactions between visual cortex and these areas, both in the context of attention, and with respect to eye movements.

He recently co-edited a large reference book entitled the Neurobiology of Attention with Laurent Itti and John Tsotsos, and is the author of numerous articles and invited reviews on the functional imaging of consciousness.

He is a member of the board of the Association for the Scientific Study of Consciousness, and was the main organizer of its tenth annual meeting that was held at St. Anne's Collge, Oxford in June 2006.
