Figure 6. An SG neurone from the segment L3 with dominating Aδ-fibre input.

Left, EPSCs recorded in one L3 SG neurone after the stimulations of L1–L6 dorsal roots with 1 ms pulses. Holding potential was −70 mV. Middle, roots giving monosynaptic inputs (L3, L4 and L5) were also tested with 50 μs pulses. Holding potential was −70 mV. Right, suggested organization of monosynaptic C- and Aδ-fibre inputs to this SG neurone from the L3, L4 and L5 segmental dorsal roots.
