What Does The Reticular Formation Do
The reticular formation is divided into three columns. Earlier no particular function was known to be associated with the reticular formation.

Raphe nuclei median gigantocellular reticular nuclei medial zone and parvocellular reticular nuclei lateral zone.
What does the reticular formation do. The reticular formation consists of a vast number of small interconnected neurons occupying the central area of the brainstem. Motor control sensory control visceral control and control of consciousness. The raphe nuclei are the place of synthesis of the neurotransmitter serotonin which plays an important role in mood regulation.
How does the reticular activating system work. The reticular formation is a collection of neuronal cell bodies of various sizes and a plethora of processes that form an ill defined meshwork in the central core of the brainstem. The ascending reticular formation is responsible for sleep cycles and is also called reticular activating system.
The reticular formation contains long ascending i e. It passes through the medulla pons and stops in the midbrain. The reticular formation is a comprehensive network of nerves found in the central area of the brainstem.
Reticular formation as the name suggests is a network of neurons and nerve fibers present in the brain. Veterinary neuroanatomy and clinical neurology third edition 2009. Today the reticular formation is considered to play a very important role in different activities of the brain and the nervous system.
Its functions can be classified into 4 categories. Traveling from the brain to the body tracts. Reticular formation neurons are also important for facilitating the operation of muscles that allow for emotional facial expressions like laughing or crying as well as for coordinating eye movements.
It s involved in many of the essential functions of the body such as the ability to obtain recuperative sleep sexual arousal and the ability to focus on tasks without being easily distracted. Traveling to the brain and descending i e. It receives afferent connections from lower centers that is spinal cord via spinoreticular and spinothalamic tracts and medical lemniscus.
The reticular formation is a portion of the brain that is located in the central core of the brain stem. Reticular formation receives afferent or incoming pathways both from spinal cord and upper centers. Parts of the reticular formation hypothalamus and thalamus excite the cerebral hemispheres and keep the cerebral cortex active and alert partly in response to noxious input.
The descending reticular formation affects your posture and autonomic nervous. It also receive afferent fibers from the cranial nuclei of vestibular acoustic and visual pathways.
