Fabrication of the Composite Regenerative Peripheral Nerve Interface (C-RPNI) in the Adult Rat

Overview

This manuscript presents a novel biologic method for creating a closed loop neural feedback system known as the composite regenerative peripheral nerve interface (C-RPNI). This system enhances motor signals while providing sensory feedback, potentially improving prosthetic device functionality for amputees.
