Telencephalic projections of the nucleus rotundus in the pigeon (Columba livia)

The nucleus rotundus receives a massive ascending projection from the optic tectum. Stereotaxic lesions were placed in the nucleus rotundus and its efferent projections studied by means of the Nauta‐Gygax and Fink‐Heimer methods for degenerating axons and terminals. Efferent rotundal axons form the lateral part of the fasciculus prosencephali lateralis (FPL), pass through the lateral portion of the paleostriatum primitivum (PP) and augmentatum (PA) and enter the overlying ectostriatum.
