Question

Quizplus · Accepted Answer

The reticular activating system (RAS) is a network of neurons that extends from the brainstem to the thalamus and is responsible for maintaining wakefulness and controlling the sleep-wake cycle. It filters out irrelevant sensory information and allows important information to pass through to the cortex for further processing. It does not directly integrate sensory information or bind fragments of information to create a conscious experience.
