The reticular formation is a set of interconnected nuclei that are located throughout the brainstem.It is not anatomically well defined, because it includes neurons located in different parts of the brain.The neurons of the reticular formation make up a complex set of networks in the core of the brainstem that extend from the upper part of the midbrain to the lower part of the medulla oblongata. In fact, it makes up the brainstem core (tegmentum) between the nuclei of the cranial nerves and the ascending and descending nerve pathways. damage to the Reticular Formation can result in prolonged coma, minor epilepsy, or narcolepsy. The reticular formation is home to several groups . This part of the central nervous system, spread in three main columns from one end of the brainstem to the other, is a core relay point that connects the nerves of the spinal cord .

It is essential for governing some of the basic functions of higher organisms, and is one of the phylogenetically . Reticular Formation. The reticular (from the Latin reticulum, meaning net) formation is a far-reaching network of neurons extending from the spinal cord to the thalamus, with connections to the medulla oblongata, midbrain (mesencephalon), pons, and diencephalon. [1] These circuits function to allow the brain to modulate between slow sleep rhythms and fast sleep rhythms, as seen on EEG. The nerve fibers in these pathways act in the spinal cord to block the transmission of some pain signals to the brain, activating the endogenous opioid system. Location. It extends throughout the length of the brainstem, along the central axis, from the it does so by influencing the activity of the alpha and gamma motor neurons through the reticulospinal and reticulobulbar tracts.
