Resting Membrane Potential |
Voltage difference across plasma membrane when cell is at rest. (Vm) |
|
Nernst Equation |
Ei = RT/zF ln[i]_o / [i]_i |
|
Graded Potentials |
Local changes in the membrane potential that decay over short ranges. Usually due to consequence of synaptic transmission and opening of non-voltage gated ion channels Bi-directional |
|
Depolarization |
Decreases membrane potential and makes it more positive than at rest. |
|
Hyper polarization |
Increases membrane potential and makes it more negative than at rest. |
