formatio reticularis medullae oblongatae
reticular formation of medulla oblongata: the phylogenetically old part of the medulla oblongata which has a reticular structure, i.e., which is composed of diffuse aggregations of nerve cells in the midst of a wealth of nerve fibers and, with certain exceptions, lacks circumscribed cell groups; it fills the spaces between the major nuclei and fiber tracts.
