Nociceptor subtypes and their incidence in rat lumbar dorsal root ganglia (DRGs): focussing on C-polymodal nociceptors, Aβ-nociceptors, moderate pressure receptors and their receptive field depths
2019, Current Opinion in PhysiologyCitation Excerpt :The CAP peak A-wave CV of sciatic nerve in 300–450d old rats is 1.9 times that of 50-60d rats [18]; our rats were approximately seven week 140–160 g female rats; 2) our CV recordings were at ∼30°C; sciatic nerve conducts ∼1.24 times faster at 37°C than at 30 °C [18]. 3) CVs were measured along the dorsal root to the soma; rat peripheral nerve A-fibers conduct on average ∼1.14 times faster than in dorsal root of the same neuron [13]; consistent with this, in peripheral nerve in similar aged rats Aδ fibers conducted up to 8 m/s, and Aαβ-fibers conducted at >14 m/s [14]. A calculation using the above proportions would increase our dorsal root 6.5 m/s Aδ-Aαβ-borderline in older >300gm rats in peripheral nerve to 14 m/s (6.5 × 1.9 × 1.14 = 14 m/s) at 30℃, or to 17.4 m/s (14 × 1.24 = 17.4 m/s) at 37°C.
The intriguing nature of dorsal root ganglion neurons: Linking structure with polarity and function
2018, Progress in NeurobiologyCitation Excerpt :In cats, by EM analysis, central and peripheral myelinated axons were shown to have similar diameters (Fadic et al., 1985; Ochs et al., 1978), whereas by intracellular labeling, myelinated central axons were shown to have a smaller diameter (Lee et al., 1986), similarly to myelinated rat axons assessed by EM (Suh et al., 1984). An increased diameter on both myelinated and unmyelinated peripheral axons is consistent with their higher nerve conduction velocity (Waddell et al., 1989). The mechanisms underlying the central-peripheral differences in DRG axon diameter are still obscure.
Partial nerve injury induces electrophysiological changes in conducting (uninjured) nociceptive and nonnociceptive DRG neurons: Possible relationships to aspects of peripheral neuropathic pain and paresthesias
2012, PainCitation Excerpt :These borderlines were defined from compound AP recordings from L4/L5 dorsal roots of female rats of the same age/weight and at the same pool temperature [28]. They were relatively low, for reasons including use of the dorsal root for CV measurements [74], the pool temperature (∼30°C), and inclusion of utilization time. For further details see [23].
