Neural basis of visual consciousness

Department of Cognitive Neurology

We investigate the neural mechanisms underlying conscious visual perception. Projects in this theme exploit visual illusions to dissociate sensation from perception and aim to understand the contribution of neuronal interactions on different temporal and spatial scales to visual awareness. We currently focus on testing whether identified neural correlates of consciousness are observable in human EEG/fMRI recordings, how much they depend on behavioral report and how neural variability affects perceptual states.
