Cognitive neuroscience of attention & awareness

Our group focuses on the cognitive neuroscience of consciousness in humans, with a particular interest in understanding the relationship between visual attention and visual awareness. The group comprises both clinicians and scientists, and we study both normal subjects and individuals with cognitive deficits following focal cortical damage from stroke. We primarily use functional MRI at low (1.5T), high (3T) and very high (4.7T) field strengths, in combination with behavioral experiments, visual psychophysics and transcranial magnetic stimulation. Members of the group are based in the Institute of Cognitive Neuroscience and the adjacent Functional Imaging Laboratory and have full access to all the facilities of both buildings.


PhD projects are designed around the interests of the laboratory and tailored to fit the individual student. Specific topics under investigation in the laboratory at present include the neural basis of binocular rivalry; neural correlates of conscious and unconscious vision in parietal extinction; attentional modulation of visual awareness in masking; the neural basis of attentional capture; and the interaction between eye position and eye movements and the visual system. Shorter (rotational) projects will encompass a short series of behavioral experiments or a single functional imaging experiment in one of these areas.
