The projection from the nucleus of the posterior commissure to the superior colliculus of the cat: patch-like endings within the intermediate and deep grey layers.
The nucleus of the posterior commissure projects to the intermediate (SGI) and deep (SGP) grey layers of the ipsilateral superior colliculus throughout its rostral-caudal dimension. This projection terminates in a patchy, discontinuous, manner. The patches form a tier in the dorsal half of SGI, and are smaller medially than laterally. These results are discussed in relation to other patchy projections to SGI and in relation to a possible modular organization of the superior colliculus.
