The ascending connections of the torus semicircularis central nucleus in Chrysemys scripta elegans.
Horseradish peroxidase was injected into the torus semicircularis central nucleus of the red-eared turtle Chrysemys scripta elegans. The following observations were made. Axons originating in the central nucleus project ipsilaterally through the tectoreuniens tract to the ipsilateral nucleus reunions. A second tract leaves the central nucleus medioventrally, courses under the floor of the cerebral aqueduct and terminates as an axonal field in the contralateral central nucleus. Finally, there was a small pathway to the deep layers of the ipsilateral optic tectum.
