…Any factor that causes a change in the resting potential acts as a stimulus to the cell. When a stimulus acts on a neuron, the resting potential (local potential) of a small part of the neuron changes, and when the magnitude of the change becomes smaller than a certain value, an action potential or spike is generated. This spike potential follows the all or none law. … *Some of the terminology explanations that mention "local potential" are listed below.

…静止電位の変化を起こさせるような要因は,その細胞に対する刺激として働く。ニューロンに刺激が働いて,ニューロンのある小部分の静止電位(局所電位local potential)が変化し,その大きさが一定値よりも小さくなると,活動電位action potentialないしスパイクspikeが発生する。このスパイク電位は全か無の法則(悉無律(しつむりつ)all or none law)にしたがう。… ※「局所電位」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
