Time Constant, ms | −40 mV | −60 mV | −80 mV | −100 mV | P |
---|---|---|---|---|---|
Type A | 61.3 ± 12.8 (5) | 25.2 ± 7.1 (14) | 19.8 ± 3.7 (9) | 13.7 ± 5.6 (6) | 0.0001 |
Type B | 29.4 ± 19.3 (6) | 14.7 ± 7.1 (25) | 10.4 ± 4.4 (15) | 6.4 ± 3.4 (7) | 0.0001 |
P | 0.0116 | 0.0001 | 0.0001 | 0.0144 |
Values are means ± SD with the number of experiments in parentheses. Time constant, single exponential fit to the experimental data; −40, −60, −80, and −100 mV, holding potentials. Pvalues were obtained using 2-sided unpaired t-test for comparison between the type A and type B neurons and 1-way analysis of variance for comparison between different holding voltages.
