The process in which membrane potential changes in the depolarizing direction from the resting potential, usually from negative to positive. For example, the initial depolarization during the rising phase of an action potential is in the direction from the negative resting potential towards the positive membrane potential that will be the peak of the action potential. The accomplishment of a non-fluctuating membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Any process that modulates the establishment or extent of the mitochondrial membrane potential, the electric potential existing across the mitochondrial membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Any process that modulates the establishment or extent of a membrane potential in the polarizing direction towards the resting potential, usually from positive to negative. Any process involved in the maintenance of an internal steady-state of ions at the level of a cell. Any process involved in the maintenance of an internal steady-state of ions within an organism or cell. Any process that modulates the establishment or extent of the postsynaptic membrane potential, which is generated by changes in the membrane potential of the post synaptic neuron that receives information at a synapse. The presynaptic neuron releases neurotransmitters into the synaptic cleft which bind to receptors on the postsynaptic neuron. After being bound by the neurotransmitters, these receptors can open or close an ion channel, allowing ions to enter or leave the cell and therefore altering the membrane potential of the postsynaptic neuron. Any process that modulates the establishment or extent of a resting potential, the electrical charge across the plasma membrane, with the interior of the cell negative with respect to the exterior. The resting potential is the membrane potential of a cell that is not stimulated to be depolarized or hyperpolarized. Any biological process involved in the maintenance of an internal steady-state of a chemical at the level of the cell. Any process that activates or increases the frequency, rate or extent of establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. The process in which membrane potential changes in the hyperpolarizing direction from the resting potential, usually from negative to more negative. Any process that stops, prevents or reduces the frequency, rate or extent of establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination. An action potential is a spike of membrane depolarization and repolarization that travels along the membrane of a cell. Hyperpolarization (vertebrates) or depolarization (invertebrates) of the photoreceptor cell membrane via closing/opening of cation specific channels as a result of signals generated by rhodopsin activation by a photon.
