The length of an axon is 10 mm, and its time constant is 4 msec. a voltage change at one end of the axon is 120 mv, which results in a change of about 10.35 mv at the opposite end after 4 msec. given this information, what is the length constant of the neuron? ( input answer in mm, rounded to the nearest whole number, without including the units.)
2) if the diameter of an axon is decreased, and the amount of ion channels stays the same causing membrane resistance to be largely unchanged, what would happen? (state all that apply.)
the length constant increases.
the length constant decreases.
the time constant increases.
the time constant decreases.
