Neuronale Informationsverarbeitung: Aus den eingehenden, meist chemischen Signalen werden im Neuron elektrische Potenziale – wenn die Botschaft wichtig war. Kommen genug wichtige Botschaften zusammen, sendet das Neuron selbst ein Aktionspotenzial.
Aktionspotenzial
Aktionspotenzial/-/action potential
In excitable cells (e.g., neurons or muscle cells), very rapid changes in electrical potential occur across the cell membrane. This event is the basis for signal conduction along the axon of the nerve cell. The action potential continues along the cell membrane and, according to the all-or-nothing principle, only occurs when the cell has been sufficiently excited.
