Special Seminar: Intracortical brain computer interfaces
Speaker: David Brandman, MD, PhD, FRCSC, Functional / Stereotactic Neurosurgery Fellow, Emory University, USA
Host: Kevin Petrecca
Brain computer interfaces (BCIs) are devices that decode neural information from the brain to allow people to control objects in their environment using their thoughts. The ongoing multi-site BrainGate2 clinical trial has demonstrated that people with paralysis -- from degenerative neurological diseases, spinal cord injuries, and strokes -- can reliably control computer cursors, robotic arms, and even their own paralyzed limbs. In this presentation I will discuss the principles of BCI design, modern approaches to BCI decoding algorithms, and growth opportunities for this technology.
The objectives of the talk are:
1. Describe the components of a brain computer interface (BCI)
2. Describe how an intracranial BCI can be used for communication
3. Describe some limitations in modern intracranial BCI technology
