Transfer of material from efferent axons to sensory epithelium in the goldfish vestibular system

摘要: Abstract Injection of labelled amino acid into the region facial motor nucleus goldfish produces, from 12 h onward, a selective labelling utricular neuroepithelium; hair cell holds more label than supporting cell. The blood removes over 85% injected site injection in medulla within 6 h. tracer other regions CNS does not produce radioautographic reaction on neuroepithelium. local produces utricle all types cell, and less Evidence existence efferent neurones to vestibular apparatus close is presented. It proposed that axons convey some material, synthesized at their bodies, which transferred A possible relation this material trophic effect discussed.
