title: The ultrastructure of the large granular vesicles of the frog's habenula.
abstract: Two types of large granular vesicles in the habenular nuclei of the frog Rana esculenta following aldehyde fixation are described. One type is almost completely filled by a dense droplet. The other type contains a globular substructure. Both satisfy the morphological criteria for neurosecretory granules.
