Biography
Paolo Bartolomeo, MD, PhD, is a clinical neurologist and neuroscientist with recognized expertise in the cognitive neuroscience of subjective experience and consciousness. He leads the PICNIC Lab at the Paris Brain Institute. His research has made high-impact contributions to understanding the structural and functional neuroanatomy of attention, perception, and mental imagery. His work employs a multidisciplinary approach integrating cutting-edge behavioral assessments, advanced neuroimaging, and neurostimulation techniques. His investigations, spanning healthy individuals and patients with brain injuries, have provided insight into the neural basis of conscious experience, cognitive recovery in stroke, and the dynamic interactions between perception and attention.
Research
Attention allows us to explore our environment. Many patients with a lesion of the right hemisphere of the brain find themselves living in a severed world, as they suffer from neglect (inattention) of the left side of the space. Neglected patients are not aware of the left half of their environment and have poor functional outcomes. To understand the brain's mechanisms of attention and consciousness, we study these patients and healthy participants. Our research uses several advanced methods, including neurophysiological techniques (intracerebral and MEG recordings), neuroanatomical techniques (high-resolution MRI) and behavioural techniques (manual response time and eye tracking). The long-term goal of our research is to bridge the gap between visual neuroscience and the clinical neurology of attention and other visual abilities.
