Answer (1 of 2): RAS stands for Reticular Activating System which is present in the base of your brain. Diffusion tensor tractography (DTT), which is derived from diffusion tensor imaging (DTI), is one of the most remarkable recent advances in neuroimaging. The thalamus plays a central role in the dynamic core.
The primary components of the RAS are found in--or arise from--the reticular formation. The reticular formation may be best known for its role in promoting arousal and consciousness. Lesions to major pathways of the reticular activating system can thus impair consciousness, and severe damage can cause coma or a persistent vegetative state. The Reticular Activating System (RAS, also called extrathalamic control modulatory system) controls everything from wakefulness (orexin/histamine) to focus (dopamine/glutaminergic), fight and flight activation, and how we perceive the world. sensory axons that project to the cerebral cortex, both directly and through the thalamus .
The ARAS is a part of the reticular formation and is . It controls sleep-wake cycles, body temperature, blood pressure, and heart rate. This function is mediated by the reticular activating system (RAS), also known as the ascending arousal system.

The reticular activating system is responsible for arousal and for governing the waking/sleeping transition (Magoun, 1952).
R. Thus, the RAS can control most aspects of the Central Nervous System (CNS). It's easy and only takes a few seconds.
Without this filter, we would all be over stimulated and distracted by noises from our environment around us. This is a honeycomb-like structure, consisting of round pigmented lines and lighter hypopigmented holes, forming a subtle pattern that appears in many melanocytic lesions. The reticular formation is the primary regulator of arousal and consciousness. ARAS abbreviation stands for Ascending Reticular Activating System.

Pldamondatok, kiejts s fordtsi gyakorisg egy helyen. The level of consciousness and arousal are controlled by the reticular formation. The "ascending reticular activating system" theory proposed that neurons in the upper brainstem reticular formation project to forebrain targets that promoted wakefulness. These pathways from the reticular formation must be functional for normal attentional abilities and sleep-wake cycles to be preserved. Switching between paradoxical sleep (REM-sleep) and slow wave sleep occurs in the . Models of systems that alternate between two states, such as sleep and awake, are often drawn as consisting of two groups of neurones, each promoting one state, and connected by inhibitory pathways.
