Conclusions on brain-machine interfaces for communication and rehabilitation are set out in Nature
The paper explores various invasive and non-invasive techniques for brain-machine control, mainly EEGs, and, more recently, those involving near infrared spectroscopy. Brain-machine assistive interfaces are designed to enable paralysed patients to communicate with or control external robotic devices such as prostheses; brain-machine interfaces for rehabilitation are designed to facilitate neuronal function recovery. This review provides a summary of the development of brain-machine interfaces and of the technology that is currently awaiting clinical studies. It deals firstly with the use of brain-machine interfaces for communication in paralysed patients, in particular in those with locked-in syndrome resulting from amyotrophic lateral sclerosis. The use of brain-machine interfaces for motor rehabilitation following a serious cerebrovascular accident or stroke and damage to the spinal cord are discussed. The possible neurophysiological and learning mechanisms underpinning the clinical effectiveness of brain-machine interfaces are also described.
