Definition: | A fibre tract in the ear called the olivocochlear bundle. It constitutes an efferent system, or feedback loop, by which nerve impulses, thought to be inhibitory, reach the hair cells. This system, which uses acetylcholine as a neurotransmitter, is presumably involved in sharpening, or otherwise modifying hearing. |
