Efferent projections of the torus semicircularis to the medulla of the tadpole, Rana catesbeiana.

Abstract:

:Horseradish peroxidase injections into the medulla of tadpoles demonstrate, by back-filling, efferent neurons in the torus semicircularis which project to the ipsilateral superior olive. This projection, as well as one to the vicinity of the efferent neurons of the contralateral VIII and lateral line nerves, is confirmed by tracing anterograde transport following HRP injections into the torus semicircularis. These efferent neurons, located primarily in the principal nucleus of the torus within the terminal field of the projection from the superior olive, represent the only reported descending path to the superior olive and efferent nuclei in a non-mammalian vertebrate.
