rostral layer --> rostral lamina

A whitish line appearing on perfectly median sections of the brain as a thin bridge connecting the rostrum of the corpus callosum with the lamina terminalis; the rostral lamina contains no commissural fibres; instead, it corresponds to the line along which the pia mater reflects from the medial surface of one hemisphere to that of the other.

Synonym: lamina rostralis, rostral layer, teniola corporis callosi.
