And if we move up the scale, if we go from negative to something positive, this process would be called depolarization. That just means going from some negative number up towards something positive.

Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane, while depolarization is when the membrane potential becomes less negative …

Get a clearer idea of what a "Depolarization Wave" means and how it goes from cell to cell through the entire heart! Rishi is a pediatric infectious disease physician and works at Khan Academy.

Britain also formed alliances with Native American groups in the Northwest Territory, the area that includes present-day Illinois, Indiana, Ohio, Michigan, and Wisconsin.

First, there's the wave of depolarization from opening up the voltage gated sodium channels. So a wave of depolarization rapidly spreads down the axon, but following right behind it, right on its heels, is this …

These incoming ions bring the membrane potential closer to 0, which is known as depolarization. An object is polar if there is some difference between more negative and more positive areas. As …

So depolarization is the idea of going from a negative membrane potential to something much more positive. And when you depolarize is when the muscle cell can squeeze down.

In many cases, they can carry current in both directions so that depolarization of a postsynaptic neuron will lead to depolarization of a presynaptic neuron. This kind of bends the definitions of presynaptic …
