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).
Depending on their function, nerves are known as sensory, motor or mixed. Sensory nerves, or afferent nerves, carry information from the periphery of the body to the brain and spinal cord. Sensations of heat, cold, pressure and pain are conveyed by the sensory nerves.Motor nerves, or efferent nerves, transmit impulses from the brain and spinal cord to the periphery, especially the muscles.ogether, the nerves make up the peripheral nervous system, as distinguished from the central nervous system, which consists of the brain and spinal cord. There are 12 pairs of cranial nerves, which carry messages to and from the brain. Spinal nerves arise from the spinal cord and pass out between the vertebrae.
