reticular nuclei of mesencephalon

[TA]
diffusely arranged cell groups located in the posterior and more medial area of the tegmentum of the mesencephalon. These nuclei are: cuneiform nucleus [TA] (nucleus cuneiformis [TA]), subcuneiform nucleus [TA] (nucleus subcuneiformis [TA]), parapeduncular nucleus [TA] (nucleus parapeduncularis [TA]), and the pedunculopontine tegmental nucleus [TA] (nucleus tegmentalis pedunculopontinus [TA]). This latter nucleus can be divided into a compact part [TA] or compact subnucleus [TAalt] (pars compacta [TA]) and a dissipated part [TA] or dissipated subnucleus [TAalt] (pars dissipata [TA]).

cuneiform nucleus

A nucleus in the midbrain reticular formation lying directly under the superior and inferior colliculi. Axons from the cuneiform nucleus project widely, caudally as far as the hindbrain and rostrally as far as the the diencephalon.
