Neurosalience #S2E12 with Maurizio Corbetta - Attention, clinical use of neuroimaging, and a provocative theory for what resting state fMRI actually is

Maurizio Corbetta is Full Professor and Chair of Neurology in the Department of Neuroscience at the University of Padua, Italy. He is also the founding director of the new Padua Neuroscience Center, a highly interdisciplinary research programme centered on the idea of brain networks in health and society.

After receiving is M.D. from the University of Pavia in Italy, he carried out a residency in Neurology at the University of Verona. In 1990 he moved to US, carting out a fellowship in NeuroImaging at Barnes Hospital at Wash U in St. Louis. While in St. Louis, he worked his way up to being the Norman J. Strupp Professor of Neurology, and Professor of Radiology, Anatomy, Neurobiology Bioengineering and Neuroscience at Wash University, as well as Director of Stroke and Brain Injury Rehabilitation at the Rehabilitation Institute of St. Louis. He moved back to Italy, to teh University of Padua, in 2016.

Prof. Corbetta has pioneered experiments on the neural mechanisms of human attention using Positron Emission Tomography (PET). He has discovered two brain networks dedicated to attention control, the dorsal and ventral attention networks, and developed a brain model of attention. His clinical work has focused on the physiological correlates of focal injury. He has developed a pathogenetic model of the syndrome of hemispatial neglect.

He is currently developing novel methods for studying the functional organization of the brain using functional connectivity MRI, magneto-encephalography (MEG), and electro-corticography (EcoG). He is also working on the effects of focal injuries on the network organization of brain systems with an eye to neuromodulation. He is known for the high level of rigor and deep insight of his research, and has over 16 papers with over 1000 citations.

Discussion

In our conversation, we discuss some of the key people that influenced him, the incredible team of people at Washington University, as well as some of his early work. We also discuss his perspective on the utility and information in resting state fMRI. He’s senior author of one of the most provocative and compelling explanations for resting state activity that I’ve seen: titled The secret life of predictive brains: what’s spontaneous activity for? Pezzulo et al TICS 2021. We go on from there to discuss his perspective of the substantial importance and profound potential of systems level neuroimaging to not only basic neuroscience but also to clinical practice. Toward the end of our discussion, he highlights how diagnosis and treatment of stroke with neuromodulation can leverage current state of the art neuroimaging techniques.
