Vestibular projections to the nucleus intercalatus of Staderini mapped by retrograde transport of horseradish peroxidase.

Medullary afferent projections to the nucleus intercalatus of Staderini have been studied by retrograde transport of horseradish peroxidase (HRP) from highly localized injections. This nucleus receives afferent projections particularly from the medial and descending vestibular nuclei as well as from the nucleus praepositus hypoglossi of both sides. The nucleus intercalatus of Staderini represents therefore an area of integration for the vestibular systems of both sides.
