Spinal Cord and Peripheral Nerve Stimulation. Signals generated through the spinal cord and peripheral nerves in the form of nerve impulses are the information pathways that the brain learns about the environment and reacts to the stimulation (using muscle contraction such as the withdrawal reflex).
By way of the peripheral nervous system (PNS), nerve impulses travel to and from the brain through the spinal cord to a specific location in the body. The PNS is a complex system of nerves that branch off from the spinal nerve roots.he spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. It begins at the bottom of the brain stem (at the area called the medulla oblongata), and it ends in the lower back as it tapers to form a cone called the conus medullaris.
