摘要: Direct projections to the pretectum and midbrain reticular formation from auditory relay nuclei in lower brainstem were examined by retrograde anterograde tracer methods cat. After horseradish peroxidase (HRP) injection into pretectomesencephalic region (Pt-MRF), which includes caudoventral regions of rostrodorsal formation, labeled neurons seen dorsal nucleus lateral lemniscus (DLL), pericentral (PC) external (EN) inferior colliculus (IC), rostral process IC (RP) brachium (NB); no found main laminated portion central IC. Subsequently, tritiated leucine was injected DLL, EN, RP or NB for autoradiographic fiber tracing. DLL terminal labeling confined ventral portions anterior pretectal nucleus. NB, heavy observed extending dorsally Thus, 3 sectors are distinguishable Pt-MRF terms termination fibers nuclei; dorsomedial, intermediate ventrolateral sector receives arising respectively. Fibers EN terminate only (pretectal regions) sector.
