Co-Evolution of Man and Machine: Neuroprosthetics in the 21st Century

NEUROPROSTHETICS IN 21ST CENTURY

Promise of Neuroprosthesis

Develop communications pathways between the brain and external devices to restore lost sensory, motor, or other internal
neural function.                         

Use the device to bypass injury or aid  in rehabilitation

Direct contact with body’s command and control systems

Seamless, intertwining of electronics, mechanics and materials.

Biomimicry : Closely replicates physiological function.

THE NEUROPROSTHESIS DECODING THEORY

Supervised and Unsupervised learning have been the key players in BMI design.

THE NEXT GENERATION BRAIN - MACHINE INTERACTION

Intelligent behavior arises from the actions of an individual  seeking to maximize received  reward in a complex and changing world.

Perception-Action Cycle:  Adaptive, continuous process of using sensory information to guide a series of goal-directed actions.

THE NEW FRAMEWORK

Co-Adaptive BMI involves TWO intelligent  agents involved in a continuous dialogue!!!
