The reticular formation now fans around the posterior borders of the red nuclei. The trochlear nucleus is replaced with the oculomotor nucleus while the oculomotor nerve projects anteriorly. The medial, spinal and trigeminal lemnisci are all present in much the same location however the lateral lemnisci does not reach to this level.

The reticular formation is the powerhouse portion of the brain, mostly found in the brain stem. There are multiple clusters of nuclei, each responsible for different things. The reticular formation is the primary regulator of arousal and consciousness. During sleep, the center normally suppresses the individual’s level of consciousness. Efferent fibers from the reticular formation can convey sensory information to the cortex of a sleeping individual, which would awaken that person.
