Effects of temperature on features of voltage-gated outward K+ currents. A: voltage-activation time constants were obtained by fitting the outward currents with a single exponential function: 10°C (∇, n = 5); 15°C (Δ, n = 7); 20°C (•, n = 9); 25°C (♦, n = 5); and 30°C (Ο, n = 6). B: voltage-activation time constants (ms) at +110 mV: 10°C (41.8 ± 3.7, n = 5, P < 0.0005); 15°C (26.4 ± 10.8, n = 7, P < 0.0005); 20°C (6.3 ± 1.2, n = 9); 25°C (1.3 ± 0.5, n = 5, P < 0.0005); and 30°C (1.1 ± 0.2, n = 6, P < 0.0005). C: steady-state current-voltage (I-V) relations at different temperatures determined at the end of 100-ms pulses: 10°C (∇, n = 7); 15°C (Δ, n = 7); 20°C (•, n = 27); 25°C (♦, n = 7); and 30°C (Ο, n = 23). D: steady-state currents (pA/pF) at +110 mV: 10°C (76.9 ± 23.6, n = 5, P < 0.0005); 15°C (133.9 ± 37.2, n = 7, P < 0.005); 20°C (320.2 ± 135.6, n = 26); 25°C (359.7 ± 82.8, n = 5, P = 0.502); and 30°C (417.5 ± 174.3, n = 23, P < 0.05). P values were obtained from Student’s t test, compared with data at 20°C.
