nervous system
• small dorsal root ganglion neurons have a reduction in the number of FSTL1-immunoreactive vesicles
|
• firing rates are elevated in wide-dynamic range neurons and both innocuous (pressure) and noxious (pinch) stimuli induce a similar increase in firing rate
|
• the baseline of spontaneous excitatory postsynaptic current frequency in lamina II neurons is elevated
• the K+ induced frequency is increased
|
behavior/neurological
• reduced response threshold to von Frey mechanical stimuli applied to the hindpaw
|
• display exaggerated responses in both first and second phases of the nociceptive reaction after intradermal injection of 0.5% formalin
|
• reduced response latencies during radiant heat testing
