The<unk>  <unk>  also<unk>  formation of<unk> , mesencephalic<unk>  formation, tegmental<unk>  formation, formatio<unk> is (tegmenti) mesencephali) is a structure in the<unk>  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. The bundle of Gudden might be identical to the hypothalamotegmental tract. Along with the oral pontine<unk>  nucleus, the<unk>  projects to the gigantocellular<unk>  nucleus. The<unk>  is the point at which the different algedonic signals come together, ensuring that the organism is aware of potential threats.
