M. Smith et al.Figure 3. Representative examples of postsynaptic responses to repetitive presynaptic nerve stimulation in manage and long-term SCS. (A) Intracellular recording from a representative accommodating neurone with the handle group illustrates that one-to-one orthodromic transmission (presynaptic pulse quantity / postsynaptic action prospective quantity) occurred at low repetitive stimulation frequency (10/10 at 2 Hz) whereas synaptic efficacy decreased at higher nerve stimulation frequencies (43/100 at 20 Hz and 13/100 at 50 Hz). (B) In a representative example from the long-term SCS group, synaptic efficacy was additional robust than handle at higher presynaptic nerve stimulation frequencies: 92/100 at 20 Hz, and 37/100 at 50 Hz.Effects of XE991 o.(AP) recordings from person phasic neurones in preparations from long-term SCS (upper trace) and handle (decrease trace); APs evoked by intracellular pulse stimulation are shown superimposed, with their respective resting membrane potentials normalized to 0 possible on the ordinate axis (dotted horizontal line). Note that the surface area of AHP decay was smaller sized in the SCS than in the manage recording. AHP durations differed accordingly (SCS: AHPdur = 22 msec, compared with handle: 32 msec). (B) Main curves phasic neurones: summated AP recordings from long-term SCS (upper trace: mean of n = 100 cells, upward SD) and superimposed summated recordings from controls (decrease trace: mean of n = 76 cells, downward SD). The time course of AHP decay surface location (measured as much as 250 msec) was considerably smaller sized in the long-term SCS than in controls. Insetaccommodating neurones had related AHP decay surface area values in SCS and manage; same presentation as for primary curves.In a subgroup on the preparations reported above, evaluation of synaptic transmission in basal states was repeated in the course of exposure to atropine (Fig. 5A). Synaptic efficacy was drastically decreased inside the presence of atropine (atropine impact, P 0.001); this reduction occurred equally in preparations from each the handle and long-term SCS groups and at all frequencies (no significant atropine 9 group, or atropine9frequency interactions). Figure 5B illustrates the substantial atropine impact within the two groups combined (P 0.001).Differential effects of atropine around the time course of AHP decay in responses to presynaptic nerve stimulationThe relationship between the time course of AHP and nerve stimulation frequency was substantially unique in between preparations in the handle and long-term SCS groups (frequency 9 group interaction, P 0.05), with a drastically quicker time course of AHP decay at reduced stimulation frequency in long-term SCS (Fig. 6A).
