Time (msec)
a) What is the resting membrane potential?
b) Compute total cellular
R
m
in
M
. Explain your reasoning.
c) Compute
τ
m
in msec. Explain your reasoning.
d) Compute the total cellular
C
m
in pF. Explain your reasoning.
(8) Demonstrate that the units in Eq. (2.11) are the same on the left- and right-hand side of the
equation.
(9) Cellular currents are often measured in units of
μA/pF
. Explain why this may be a good measure
to use and explain how you would convert Eq. (2.11) to the proper form.
Simulation Problems
(1) Program a passive membrane with input variables of Rm, Cm, dt, endtime, Stim start, Stim End,
and Stim Strength.
(2) Program a passive membrane with input variables of Rm, Cm, dt, endtime, Stim start, Stim End,
and Stim Strength.
