This causes brief hyperpolarization of the membrane, that is, the membrane potential becomes transiently more negative than the normal resting potential.
32.
The cell uses ion channels, ion pumps, and voltage gated ion channels to generate a negative resting potential within the cell.
33.
However, the process of generating the resting potential within the cell also creates an environment outside of the cell that favors depolarization.
34.
Potassium channels are then activated, and there is an outward flow of potassium ions, returning the electrochemical gradient to the resting potential.
35.
Its binding terminates an action potential by causing an influx of chloride ions into the neuron, repolarizing the neuron to its resting potential.
36.
This resting potential undergoes rhythmic oscillations, which have been termed " slow waves ", and reflect intrinsic activity of slow wave potentials.
37.
These channels are not perfect rectifiers, as they can pass some outward current in the voltage range up to about 30 mV above resting potential.
38.
:Sure, many / most neurons, for instance, have a resting potential of around-70 mV ( really it varies widely ).
39.
The resting potential is ultimately re-established by the closing of all voltage-gated ion channels and the activity of the sodium potassium ion pump.
40.
Other changes include the lowering of the membrane s resting potential, reduction of membrane resistance, and in increase in the peak values of action potentials.
