Is the inferior colliculus and obligatory relay in the cat auditory system?

The status of the inferior colliculus of the cat as an obligatory relay in the ascending auditory pathway was examined by attempting to infiltrate totally the fibres of the brachium of the inferior colliculus on one side with horseradish peroxidase. Following a transport time of 24 h, alternate sect...

Zusammenfassung:	The status of the inferior colliculus of the cat as an obligatory relay in the ascending auditory pathway was examined by attempting to infiltrate totally the fibres of the brachium of the inferior colliculus on one side with horseradish peroxidase. Following a transport time of 24 h, alternate sections from thalamus to caudal brainstem were reacted with a sensitive histochemical method to reveal tracer reaction product. Results for three cats revealed that the inferior colliculus is an obligatory relay for the overwhelming majority of axons comprising the lateral lemniscus and originating in the cochlear nucleus and superior olive.
