Question

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? (Enter your answer in mm, rounded to the nearest whole number, without including the units.)

Answer 1

Answer: 5

I worked it out and don't feel like typing in all the equations and stuff but this is the right answer. Hope I reached out in time.
