Question A cell containing voltage dependent potassium channels has been clamped to -39mV for a long time so n has reached it's steady state value for that membrane potential. At t=0, the membrane potential is abruptly clamped from -39mV to -2mV. Using the graphs of n_inf and tau_n on the board, you will assemble the equation for n(t). First, what is the starting value of n? Answer 0.1 Question What is the asymptote of n immediately after t=0? Answer 0.45 Question
