Abstract
Die afferente Innervation zum Colliculus inferior (IC) wurde mit Hilfe des retrograden axonalen Transportes von Meerrettichperoxydase (HRP) untersucht. Nach Injektion von HRP in den zentralen Kern des IC fanden sich markierte Zellen in unterschiedlichem Ausmaß in allen auditorischen Kernen sowie im temporalen Cortex. Nahezu alle Zellen des zur Injektion ipsilateral gelegenen ventralen Kerns des Lemniscus lateralis sowie medialen Kerns des oberen Olivenkomplexes projezieren zum IC. Eine hohe Anzahl markierter Neurone finden sich auf der kontralateralen Seite im dorsalen Kern des Lemniscus lateralis sowie im dorsalen und ventralen Nucleus cochlearis. Der laterale Kern des oberen Olivenkomplexes war bilateral etwa gleich stark markiert, während unter den periolivären Zellkomplexen der dorsomediale auf der ipsilateralen Seite die stärkste Markierung zeigte. Darüber hinaus fanden sich markierte Neurone im kontralateralen IC sowie bilateral im ventralen Teil des Corpus geniculatum mediale. Die Pyramidenzellen der Schicht V im temporalen Cortex ließen sich ipsilateral stark markiert nachweisen. The innervation of the inferior colliculus in guinea pig was studied using the method of retrograde axonal transport of horseradish peroxidase (HRP). Following injections of HRP into the central nucleus of the inferior colliculus (IC) HRP labeled cells were found in all auditory nuclei as well as in the temporal cortex. Virtually all neurons of the ventral nucleus of the lateral lemniscus and the medial superior olivary nucleus ipsilateral to the injection side appear to project to the IC. A large number of labeled cells exhibited in the dorsal nucleus of the lateral lemniscus and in the ventral and dorsal cochlear nuclei contralaterally. The lateral superior olivary nucleus was evenly labeled bilaterally while among the periolivary nuclei the dorsomedial periolivary nucleus was heavily labeled ipsilateral to the injection side. Furthermore, labeled neurons occurred in the contralateral IC and in the ventral part of the medial geniculate body on both sides. The pyramidal cells of layer V of the temporal cortex were heavily labeled ipsilaterally.Keywords
