Table 2.

[Ca²⁺]_i area ratios, S2/S1, are shown at 25ºC for 0.5-s at 10-, 20-, 30-, and 40-s intervals (n = 5, 7, 9, 12, respectively) and 2-s stimuli for 10-, 20-, 30-, and 40-s intervals (n = 5, 13, 17, 14, respectively). [Ca²⁺]_i area ratios are also shown at 37ºC for 0.5-s at 10-, 20-, 30-, and 40-s intervals (n = 6, 6, 6, 7, respectively) and 2-s stimuli for 10-, 20-, 30-, and 40-s intervals (n = 5 for all intervals).
