Zusammenfassung

Evozierte Potentiale sind volumengeleitete, extrazellulär abgeleitete, elektrische Signale, die nach elektrischer oder adäquater Reizung erregbaren Gewebes auftreten. Die Messung evozierter Potentiale bietet ein nicht invasives, unschädliches Verfahren, das Aussagen über normale und pathologische Funktionen im Nervensystem des Menschen zuläßt. Latenzen und unter Vorbehalt auch Amplituden der evozierten Potentiale können zur Auswertung herangezogen werden. Beide Größen werden entscheidend von den physiologischen Vorgängen bestimmt, die räumlich-zeitlich zwischen der Auslösung und der Ableitung der evozierten Potentiale liegen (Abb.1.1 A). Auslösung, Fortleitung, Verschaltung und schließlich zentrale Verarbeitung sind die physiologischen Grundlagen evozierter Potentiale, die hier in einfacher und knapper Form abgehandelt werden sollen.
