  • 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.
