When a neurotransmitter opens a chemically gated ion channel that allows sodium to enter the postsynaptic cell, the result is an EPSP. It is an excitatory potential.
An excitatory postsynaptic potential (EPSP) is a type of potential that causes an increase in the potential due to the flow of positively (+) charged ions such as sodium ions.
The release of chemical messengers called neurotransmitters by presynaptic cells leads to the excitatory postsynaptic potential.
These neurotransmitters bind to specific cell receptors localized in postsynaptic cells.
