Figure 8.

Comparison of APs evoked by dorsal root paired-pulse stimulation and by soma current injection. The figure shows APs in one specific MS in a neuropathic animal evoked by dorsal root paired pulse stimulation and by soma current injection. A. shows a delayed second response by 2.6~ 2.9 ms at intervals of paired dorsal root stimulation and a failed response at 2.5, 2.6 ms. The actual delayed response interval was at least 5.57 ms. B. shows 7 APs in response to depolarizing current injection, with individual AP intervals of 2.71~3.24 ms.
