[6] Additionally, the corpus callosum of the human brain has a nerve tract known as the rostrum. The beak or snout of a vertebrate may also be referred to as the rostrum.

[2] A recent study of individuals with agenesis of the corpus callosum suggests that the corpus callosum plays a vital role in problem solving strategies, verbal processing speed, and executive performance. Specifically, the absence of a fully developed corpus ...
The boundary facing exterior to the ventricle curvature is formed by the corpus callosum - the floor at the limit of the ventricle is the upper surface of the rostrum (the reflected portion of the corpus callosum), while nearer the body of the ventricle, the roof consists of the posterior surface of the genu.
