34. Which of the following statement concerning “spinal cord plasticity and pain” is least likely?
(A) A strong and/or sustained activation of nociceptive C fibers may induce the plasticity in
spinal cord.
(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.
