Reticular Formation. Table 1.

Nuclei of the brainstem reticular formation

Nuclei are ordered from caudal to rostral, colored boxes indicate where the nuclei are situated in the brainstem: blue – Medulla oblongata; orange – Pons; green – Mesencephalon. At medullary levels an intermediate zone has been delineated. Whereas the zones are easily recognizable at medullary levels (caudal), it is more difficult to distinguish them at rostral pontine and mesencephalic levels. Thus, at mesencephalic levels the allocation of nuclei to distinct zones is fairly tentative. Abbreviation: n nucleus.
