Unlocking Movement: Helping Paralyzed People Use Thought to Control Computers and Robotic Limbs

A number of medical conditions can cause paralysis including spinal cord injury, stroke, neurological diseases, and traumatic brain injury. What if there was a way to help patients regain sensation and control over assistive devices using their thoughts? Brain-machine interfaces (BMIs) consist of tiny electrodes that record the activity of large numbers of cortical neurons along with artificial intelligence algorithms that can interpret a user’s intent based on neural activity. In this talk, part of Caltech’s Watson Lecture series, neuroscientist Richard Andersen, will discuss how researchers in his lab, working with collaborating colleagues, have used a novel approach of implanting electrodes in a variety of specialized cortical areas rather than just the motor cortex. Using this approach, paralyzed patients can control robotics and computers, allowing them to drink a beverage, play a computer piano, use video games and programs like Photoshop, drive an automobile, and feel touch in hands and arms that have previously been rendered insensate from spinal cord injury.

Free and open to the public, the Watson Lecture Series offers a unique opportunity to learn about cutting-edge science directly from Caltech’s premier researchers. Join us at 6PM for pre-event music, food, and activities.
