“Restoring Neurological Function: Algorithms at the Brain-Computer Interface”
Dr. Lakshminarayan Srinivasan, UCLA

Abstract
Beyond voice, touch and gesture-based computing, the prospect of directly connecting brains and computers is now beginning to materialize from a convergence of neuroscience, medicine and engineering. A truly seamless brain-computer interface (BCI) could revolutionize the treatment of stroke and other neurological diseases, seamlessly integrating electronics with the brain to recover lost function. This talk will provide an introduction to BCI design, with a focus on the algorithms that are at the core of this rapidly evolving research area. As an illustration, we will discuss the process behind extracting and decoding movement-related signals from the brain. Looking forward, the talk will highlight fundamental challenges in algorithm design that we now face in realizing the ultimate vision of a seamless BCI for the treatment of stroke and other mechanisms of nervous system injury.
