Figure 3. CBD3063 reduces total calcium currents in DRG neurons. p <0.05; Multiple Mann-Whitney tests. (C) Summary of bar graph showing peak calcium current densities (pA/pF).p value as indicated; Mann-Whitney test. (D) Boltzmann fits for voltage-dependent activation and inactivation as shown. Half-maximal activation potential of activation and inactivation (V1/2 ) and slope values (k ) for activation and inactivation are presented in Table 2 . N=13-16 cells; error bars indicate mean ± SEM.
