Zusammenfassung

Die Untersuchung des Gehörsinns ist gerade mit der funktionellen Magnetresonanztomographie (fMRT) ein technisch schwieriges Unterfangen, da das Gerät während der Messung einen hohen Geräuschpegel verursacht. In diesem Artikel werden technische Rahmenbedingungen beschrieben, die das Prüfen der Hörverarbeitung dennoch ermöglichen. Weiterhin werden jene Schaltstellen der Hörbahn und die involvierten kortikalen Areale bildhaft beschrieben, die einer Untersuchung des Hörsinns technisch zugänglich sind.

Abstract

Examination of the sense of hearing is a technically difficult undertaking especially with functional magnetic resonance imaging because the machine causes a high noise level during the measurement. This article describes the technical conditions which, nevertheless, allow the auditory capabilities to be tested. Furthermore, every switch point of the auditory pathway and the cortical areas involved, which are technically accessible in an investigation of the sense of hearing are pictorially described.
