The midbrain reticular formation (mesencephalic reticular formation, tegmental reticular formation, formatio reticularis (tegmenti) mesencephali) is a structure in the midbrain consisting of the dorsal tegmental nucleus, ventral tegmental nucleus, and cuneiform nucleus. These are also known as the tegmental nuclei.

The dorsal and ventral tegmental nuclei receive connections from the mammillo-tegmental bundle of Gudden, a branch of the mammillothalamic tract

Mammillothalamic tract

The mammillothalamic fasciculus arises from cells in both the medial and lateral nuclei of the mammillary body and by fibers that are directly continued from the fornix.The Mammillothalamic fasciculus then connects the mammillary body to the dorsal tegmental nuclei, the ventral...

. The bundle of Gudden might be identical to the hypothalamotegmental tract

Hypothalamotegmental tract

The hypothalamotegmental tract is a pathway from the hypothalamus to the reticular formation. Axons from the posterior hypothalamus descend through the mesencephalic and pontine reticular formations. They connect with reticular neurons important in visceral and autonomic activity. The tract is a...

Oral pontine reticular nucleus

The oral pontine reticular nucleus is delineated from its caudal brother, with which it shares its first three names.This nucleus tapers into the lower mesencephalic reticular formation and contains sporadic giant cells....

  NeuroNames is an integrated nomenclature for structures in the brain and spinal cord of the four species most studied by neuroscientists: human, macaque, rat and mouse. It offers a standard, controlled vocabulary of common names for structures, which is suitable for unambiguous neuroanatomical...
