The statement that the cell bodies of sensory neurons are found in an enlarged area of the dorsal root called the gray commissure is false because the cell body is called a DORSAL ROOT GANGLION.
From the peripheral nervous system, dorsal nerve roots provide sensory neural signals to the central nervous system. Anatomically, the dorsal root of the spinal nerves gives rise to a dorsal root ganglion. They transport sensory information from numerous peripheral receptors in order for the central nervous system to respond. The function of DRG in chronic pain is well known. Anesthesia infiltration of the DRG was first described in 1949. The dorsal root entry zone (DREZ), a nearby related neural target, dorsal rhizotomy or gangliectomy, conventional radiofrequency denervation, pulsed radiofrequency, and steroid injection have all been used to target the DRG.
