Detection and evaluation of brain spinal cord conduction function based on functional electrical stimulation

Objective: The purpose of this study is to detect and evaluate the brain and spinal cord conduction function in rats with functional electrical stimulation (FES) technique, and to provide a practical simple atlas for electrode implantation in the microelectronic neural bridge system.Methods: FES was performed on the brain and spinal cord of 16 SD rats, and the normalized coordinate spinal signals of nerve and the types of evoked motion were recorded. Results: (1) The FES technique could activate the core area of spinal cord and induced the lower limb movement of key muscle. (2) The spinal cord conduction function of the rat primary motor cortex nerves in the brain and spinal cord could be assessed by Cerebus system.Conclusions: FES can activate multiple sets of spinal nerve fibers and to complete special action.
