(B) The cholera toxin B subunit is the primary marker used for sprouting of injured primary nerves.
(C) During inflammatory pain, the dorsal root ganglion in the involved nerve show similar changes as seen in neuropathic pain.
(D) Peripheral nerve injury may cause ongoing activity and after-discharges.
(E) The overall increased excitatory drive may be combined with a compromised inhibitory control in the dorsal horn.
