Speaker: Edward Chang, PhD

Professor, Neurological Surgery, UCSF Weill Institute for Neuroscience, USA

Abstract: Speech is a defining human behavior. Therefore, speech loss resulting from paralysis or aphasia can be devastating. Over the last decade, tremendous progress has been made in understanding the neural representation of speech articulation with approaches such as direct intracranial cortical recording and stimulation, lesion-behavior correlation, and imaging. The new findings radically challenge several long-held models of language organization, including the role of Broca’s area and the “homunculus” functional organization of the precentral gyrus. In this talk, I will present evidence for an emerging new model of how the cortex coordinates speech production.

Bio: compression syndromes such as trigeminal neuralgia and hemifacial spasm. He is Chairman of the Department of Neurological Surgery at UCSF. Dr Chang specializes in advanced brain mapping methods to preserve crucial areas for speech and motor functions in the brain. He also has extensive experience with implantable devices that stimulate specific nerves to relieve seizure, movement, pain and other disorders. Dr Chang's research focuses on the brain mechanisms for speech, movement and human emotion. He co-directs the Center for Neural Engineering and Prostheses, a collaborative enterprise of UCSF and the University of California, Berkeley. The center brings together experts in engineering, neurology and neurosurgery to develop state-of-the-art biomedical technology to restore function for patients with neurological disabilities such as paralysis and speech disorders. Dr Chang earned his medical degree at UCSF, where he also completed a residency in neurosurgery. He was honored with the Blavatnik National Laureate for Life Sciences in 2015, in recognition of his contributions to deciphering the neural code of speech. Dr. Chang is the inaugural Bowes Biomedical Investigator at UCSF and HHMI Faculty Scholar. Dr Chang was inducted to the National Academy of Medicine in 2020.
