Neurophysiology of Nerve Impulses. Physioex 31. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became less negative because les...
