Topographical representation in rabbit cerebellar flocculus for various afferent inputs from the brainstem investigated by means of retrograde axonal transport of horseradish peroxidase.
A small amount of horseradish peroxidase (HRP) was injected into several small areas of the flocculus and adjacent ventral paraflocculus of albino rabbits. Labeled cells were surveyed through the inferior olive, vestibular nuclear complex, nucleus reticularis tegmenti pontis, pontine nucleus and abducens nucleus. Distribution of labeled neurons in these structures varied depending on the location of injection sites, indicating the existence of a fine topographical organization for afferent inputs in the flocculus and adjacent ventral paraflocculus.
