In a typical mammal neuron, the membrane potential must surpass to produce an action potential. At this point, what happens to the sodium activation gate

Voltage threshold

Explanation:

The action potential threshold or voltage threshold is the minimum voltage that the membrane must reach to cause the mass opening of voltage-dependent sodium channels, that is, to trigger an action potential.

The frequency of action potentials, on the other hand, depends on the intensity of the original stimulus.

Only stimuli  significant enough to exceed the threshold are transmitted as information and encoded in the form of  action potentials along the axon to other neurons.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
