In this talk Dr. Miguel Nicolelis describes how state-of-the-art research on brain-machine interfaces make it possible for the brains of primates to interact directly and in a bi-directional way with mechanical, computational and virtual devices without any interference of the body muscles or sensory organs.
Join Dr. Nicolelis (Beyond Boundaries: The New Neuroscience of Connecting Brains with Machines---and How It Will Change Our Lives, Times Books, 2011) as he reviews a series of recent experiments using real-time computational models to investigate how ensembles of neurons encode motor information. These experiments have revealed that brain-machine interfaces can be used not only to study fundamental aspects of neural ensemble physiology, but they can also serve as an experimental paradigm aimed at testing the design of novel neuroprosthetic devices.
He will also describe evidence indicating that continuous operation of a closed-loop brain machine interface, which utilizes a robotic arm as its main actuator, can induce significant changes in the physiological properties of neural circuits in multiple motor and sensory cortical areas. This research raises the hypothesis that the properties of a robot arm, or other neurally controlled tools, can be assimilated by brain representations as if they were extensions of the subject's own body.
Dr. Nicolelis is Professor, Neurobiology Biomedical Engineering and Psychological and Brain Sciences,Co-Director, Center for Neuroengineering, at Duke University. He received his medical degree from the University of Sao Paulo Medical School, and was awarded a Ph.D. from the Institute of Biomedical Science, University of Sao Paulo.
