What is the reticular activating system?
PsychologyBrainstem
Quick Answer
The reticular activating system is a network in the brainstem involved in wakefulness, alertness, and attention. It helps keep the brain responsive to important stimuli.
The Full Story
The reticular activating system, often shortened to RAS, is part of the reticular formation in the brainstem. It plays a key role in arousal and in filtering incoming signals that support attention and consciousness. Although the exact circuitry is complex, the concept is widely used in neuroscience and medicine to describe brainstem systems that maintain wakefulness. Damage to these pathways can seriously impair alertness and consciousness.
