Imagine you insert a stimulating electrode into a "typical" neuron in your arm, so that you can inject any amount of depolarizing or hyperpolarizing current that you want into the cell. Assume for the sake of this question that doing so will not alter the ionic concentration gradients in your tissue, kill the cell, or damage any of the normal components of the cell. Is there any way that you could create a situation where K⁺ ions were diffusing on net from the extracellular fluid into this neuron?
