Which of the following occurs during depolarization?
In biology depolarization (British English: Depolarisation) is a change within a cell during which the cell undergoes a shift in electric charge distribution resulting in less negative charge inside the cell. Depolarization is essential to the function of many cells communication between cells and the overall physiology of an organism. Most cells in higher organisms maintain an internal environment that is negatively charged relative to th…
Action potentials result from the presence in a cell's membrane of special types of voltage-gated ion channels. A voltage-gated ion channel is a cluster of proteins embedded in the membrane that has three key properties: 1. It is capable of assuming more than one conformation.

In neuroscience an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential.This temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell is a result of opening ligand-gated ion channels.
These sodium channels are voltage-dependent opening rapidly due to depolarization of the membrane which usually occurs from neighboring cells through gap junctions. They allow for a rapid flow of sodium into the cell depolarizing the membrane completely...
