The reticular formation it's a 'diffuse net' which is formed by nerve cells and fibers it extends from the neuroaxis spinal cord through medulla, pons, midbrain, subthalamus, hypothalamus and thalamus (spinal cord is relayed superiorly to the cerebral cortex) many afferent and efferent pathways project in and out of the rf from most parts of.

Before discussing the anatomy of the brain i just want you to realize that at this level exact areas of the brain are not all that important as long as you understand the general function and the only structure you have to know in the midbrain is called the reticular formation.
