Q

Reticular activating system RAS

A

Network of neurons in the core of the brain stem, with ascending and descending tracts to other areas of the brain that monitor and regulate incoming sensory stimuli and level of arousal
RAS is highly selective
It is located between the nerve centers in the medulla oblongata and the brain stem
It is responsible for bringing together information from the sense organs
If destroyed, results in coma
