Fig. 6.
Group data of the effects of IL-1β and TNF-α on the action potential firing frequency in the SLN. The upper graph illustrates the action potential frequency with increasing concentrations of IL-1β (n = 14) and application of high-concentration sodium cyanide (CN). The lower graph depicts the same information with respect to TNF-α (n = 9). In both cases, there is no statistically significant difference between action potential frequency at baseline and at any cytokine concentration.
