Body and Machine A more profound understanding of how the brain functions has led to major advances in brain-computer interfaces (BCI). Once considered science fiction, neuroprosthetics are now helping disabled individuals rediscover -- or experience for the first time -- capacities that greatly improve quality of life. Through systems that monitor brain activity and translate it into actions such as moving a wheelchair or selecting a letter from a virtual keyboard, people with disabilities are exploring the world in new ways. This symposium will focus on both noninvasive interfaces, where control comes mainly from electroencephalographic (EEG) activity, as well as interfaces that incorporate implants in the brain. Both forms of prostheses restore patients' experience with the world and blur the lines between humans and machine. Future uses of these technologies may one day allow an augmented human to go far beyond the confines of the body and open new territories of possibility, particularly relevant for paralyzed humans and for people in challenging environments like space.
