Aufbau und Funktion der Hörbahn

Anatomy and physiology of the auditory pathway


Das auditive System setzt sich aus dem in der Peripherie gelegenen Ohr, in dem eine Umwandlung des Schalls in ein elektrisches Signal stattfindet, und Neuronen, die anhand von Aktionspotenzialen eine zentrale Verarbeitung durchführen, zusammen. Die wichtigsten anatomischen und funktionellen Merkmale des auditiven Systems werden erläutert. Dazu fand eine selektive Literaturrecherche in den Datenbanken PubMed (auch in der Europe PubMed Central), Psychline, Google Scholar, Cochrane Library und Web of Science statt, und zusätzliche Angaben einschlägiger Werke bzw. Websites auf den Gebieten (Neuro‑)Anatomie, (Neuro‑)Physiologie und (Neuro‑)Otologie, u. a. mit den Suchbegriffen Hörbahn, „auditory system“, „auditory pathway“, „receptors“, „spatial hearing“, „auditory cognition“ wurden mit einbezogen.


The auditory system consists of the ear located in the periphery, in which a conversion of the sound into an electrical signal takes place, and neurons, which perform central processing based on action potentials. The most important anatomical and functional features of the auditory system are explained. For this purpose, a selective literature search was carried out in the databases PubMed (also in the Europe PubMed Central), Psychline, Google Scholar, Cochrane Library and Web of Science. Additional information was obtained from relevant books or websites in the fields of (neuro)anatomy, (neuro)physiology, (neuro)ophthalmology and (neuro)otology, among others with the keywords Hörbahn, auditory system, auditory pathway, receptors, spatial hearing and auditory cognition.
