This question relates to the "Tength constant" (A) and decay of a local graded potential over DISTANCE in a dendrite. Let's say you depolarize a dendrite (of uniform diameter) at a specific site via current-injection, and the PEAK change in membrane potential (Vo) at the current injection site is 100 mV. The dendrite's length constant (A) is 150 um What will the amplitude of the depolarizing potential be at a distance (x) of 275 um from the current injection site? In other words, what will (Vx) be at a distance (x) of 275 pm? The answer should be in mv units, rounded to the nearest tenth of a millivolt.
