(B) Neurotrophic factors BDNF and NGF are thought to be able to induce hyperalgesia on spinal application.
(C) In nociceptive pathways, long-term potentiation (LTP) may be triggered by enhanced synaptic activity.
(D) LTP may be induced by electrical stimulation and nerve injury, but not hindpaw injection of formalin.
(E) In nociceptive pathways, long-term potentiation (LTP) may be triggered by abrupt withdrawal from opioids.
