The undershoot of the typical neuronal action potential is due largely to increased permeability of the plasma membrane to potassium. This job explains the answer.© BrainMass Inc. brainmass.com August 19, 2018, 2:00 am ad1c9bdddf
"During the undershoot, the membrane potential is transiently hyperpolarized because the K+ permeability is even greater than at rest. The action potential end ...
This job briefly emphasizes action potential. The typical neuronal action potential which is depicted is determined.
