Summary: Decades of research have improved the brain-computer interface to allow people with severe disabilities to communicate their thoughts through recorded electroencephalographic signals along the scalp non-invasively. Recently brain-machine interface based Neuroprosthetics for motor function has been inspired by successful demonstrations of controlling movement of computer cursors or even actual robots to perform meaningful tasks of feeding by control commands converted from cortical neuron activities from implanted intra-cortical electrode arrays. There are also active research efforts to pursue neuroprosthetic systems for recovery and enhancing sensory and cognitive functions. In this lecture we will briefly review the techniques and neurophysiological basis of brain-machine interface based approaches for motor, sensory and cognitive function recovery and improvement. Examples of successful experimental setup and data acquisition will be given. Finally we will start some discussions on limitations and future directions of the field of BMI-based Neuroprosthetics.
