Table 1. Summary of the effects of cholesterol extraction on the coupling of CaCC activity to BK- and PAR-2-induced Ca2+ release and to VGCC-mediated Ca2+ influx.
Numbers represent amount of neurons displaying a given property from the total amount of neurons tested for each condition. Significant differences based on χ2 with p < 0.05 are indicated. N/A, not analyzed
