Afferent responses after injections of a mixture of KCl and LA. Discharge variation was expressed as a percentage of the baseline discharge. In each group, significant differences between the two mixtures (5–15 mM and 10–25 mM) are indicated by *. For a given dose, significant differences between group are indicated by + . Finally, in each group, significant differences between M1 and M3 for a given dose are indicated by #. (1 symbol: p < 0.05; 2 symbols: p < 0.01 and 3 symbols: p < 0.001).
