Question

After a stimulus results in initial depolarization of a region of cell membrane of a neuron:

Answer 1

After a stimulus results in initial depolarization of a region of cell membrane of a neuron, a threshold voltage is reached. ... -Voltage-gated sodium and potassium channels quickly close, and recovery begins. A large number of voltage-gated sodium channels quickly open, causing a rapid change in membrane potential.
