Sir Victor Horsley Lecture 2026 : Dr Edward Chang

This year’s lecture “A neural code for words” will be delivered by Dr Edward Chang, Joan and Sanford I. Weill Chair of Neurological Surgery at the University of California, San Francisco.  In this lecture, Dr Chang will review fundamental discoveries that have revealed the neural computations and representations of human speech.

The National Brain Appeal is proud to support the Victor Horsley Memorial Lecture.

Dr. Chang’s clinical expertise is surgical therapies for epilepsy, pain, and brain tumors. He specializes in advanced neurophysiologic brain mapping methods, including awake speech and motor mapping, to safely perform neurosurgical procedures in eloquent areas of the brain. His research focuses on the discovery of cortical mechanisms of high-order neurological function in humans.  Dr. Chang’s laboratory has demonstrated the detailed functional organization of the human speech cortex and has translated those discoveries towards the development of a speech neuroprosthetic device to restore communication for people living with paralysis.  Dr. Chang is recipient of the 2015 Blavatnik National Laureate in Life Sciences, The Winn Prize of the Society of Neurological Surgeons, and was elected to the National Academy of Medicine and the National Academy of Sciences.
