The sympathetic ganglia, or paravertebral ganglia are autonomic ganglia, of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell bodies bring information from the brain and spinal cord to t… WebPRF consisted of 2 Hz biphasic 25 msec trains of PRF (500 kHz, 5 V intensity) applied on the right L5 dorsal root ganglion for 300 sec.
