Effect of pressure on the dynamics of MPP's FDD. (A) Similar FDD is induced by 4 mM [Ca2+]o at pressures of 0.1 MPa and 10.1 MPa. Ex were normalized with respect to their corresponding E1 (n = 6 for each condition; differences at each stimulus were not statistically significant). (B) FDD is more significant at 10.1 MPa – 4 mM [Ca2+]o than at 5.1 MPa – 2 mM [Ca2+]o, (n = 6; *p < 0.05). Note that larger FDD occurs at 10.1 MPa despite of the similarity of E1 under both conditions. All graphs show means ± SE.
