Attention allows us to explore our environment. Many patients with a lesion in the right hemisphere of the brain find themselves living in a halved word, because they suffer from neglect (inattention) for the left side of space. Neglect patients are unaware of the left half of their environment, and have a poor functional outcome. To understand the brain mechanisms of attention and awareness, we study these patients as well as healthy participants. Our research employs several advanced methods, including neurophysiological (intracerebral recordings and MEG), neuroanatomical (high resolution MRI) and behavioral techniques (manual response times and eye-tracking). The long-term goal of our research is to bridge the gap between visual neuroscience and clinical neurology of attention and other visual abilities.
