Reticular Activating system, EEG, Sleep and Arousal 1 Reticular Activating system, EEG, Sleep and Arousal Objectives to describe major divison and functions of the reticular system understand the basis of generation of the EEG to know various waves in EEG and understand the use of EEG sleep disorders of sleep Reticular formation group of interlacing network of neurons that occupy the midventral portions of medulla and midbrain originate in upper brainstem and protect through synaptic relays in the rostral intralaminar thalamic nuclei to the cerebral cortex Reticular Activating system, EEG, Sleep and Arousal 2 🧠 gamma lower motor neurons play a role in muscle tone the reticular formation has afferent and efferent connections the reticular formation plays the primary role in sleep. it is considered the main switch of the cerebral cortex if the reticular formation is activated then you will be awake. if they reticular formation is deactivated then you will sleep Physiological divisons of the reticular system ascending reticular system afferent connections efferent connections
