Reticular formation, as the name suggests, is a network of neurons and nerve fibers, present in the brain. Earlier, no particular function was known to be associated with the reticular formation. Today, the reticular formation is considered to play a very important role in different activities of the brain and the nervous system. Midbrain reticular formation.

It is involved in the control of breathing, communication between different parts of the brain, and sensations such as hearing ... The pons is responsible for several vital functions in addition to housing the reticular formation, which contains the neurons responsible for arousal and consciousness, and four cranial nerve nuclei. Brain Stem. The brain stem is a stalk-like structure that connects the cerebrum with the spinal cord and consists of the midbrain, pons, and medulla oblongata. The brain stem contains many nerves, pathways, reflex centers, and nuclei and serves as a major relay station for sensory, motor, and autonomic information.
