In the image above, you can see the entire spinal cord of the human body leading up to the base of the brain at the brainstem. Through the nerves in the spinal cord, the brain receives all of its nutrition and sensory information from the central nervous system.One of the most important parts of the spinal cord and brainstem is the reticular formation. The reticular formation is a group of neural networks that functions in maintaining sleeping cycles, cardiovascular activity, pain, certain motor control, and habituation. Damage to the spinal cord will usually result in paralysis.
