Graded force potential

WebThe most common cause of an excitatory graded potential in neurons is entry of sodium ions through neurotransmitter receptors that allow sodium ions to pass when the neurotransmitter is bound. But the mechanism would be the same for calcium ions. It would actually become positive, at which point the electrical force would switch. … A graded potential is something that is an input that occurs in the input region.
