Ascending reticular activating system. Reticular formation labeled near center. The ascending reticular activating system (ARAS), also known as the extrathalamic control modulatory system or simply the reticular activating system (RAS), is a set of connected nuclei in the brains of vertebrates that is responsible for regulating wakefulness and ...
A deficit in the level of consciousness suggests that both of the cerebral hemispheres or the reticular activating system have been injured. [4] A decreased level of consciousness correlates to increased morbidity (sickness) and mortality (death). [5] Thus it is a valuable measure of a patient's medical and neurological status.
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
It is a part of the reticular activating system in the reticular formation. [ 3 ] The locus coeruleus, which in Latin means "blue spot", is the principal site for brain synthesis of norepinephrine (noradrenaline).
The questionnaire is called the Behavioral Inhibition System and Behavioral Activation System Questionnaire. [27] People can be tested based on their activation of either systems by using an EEG. These tests will conclude whether a person has a more active BIS or BAS. The two systems are independent of each other. [15]
Subcortical brain regions associated with arousal include the basal forebrain cholinergic system, and the locus coeruleus (LC) noradrenergic system. [19] Both regions are components of the reticular activating system (RAS). The basal forebrain cholinergic system is associated with cortical acetylcholine release, which is associated with ...
Dextroamphetamine (INN: dexamfetamine) is a potent central nervous system (CNS) stimulant and enantiomer [note 1] of amphetamine that is indicated in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. [11] [28] It has also been used illicitly to enhance cognitive and athletic performance, as well as an aphrodisiac ...
For a patient to maintain consciousness, two important neurological components must function impeccably. The first is the cerebral cortex which is the gray matter covering the outer layer of the brain. The other is a structure located in the brainstem, called reticular activating system (RAS or ARAS). Injury to either or both of these ...
