Question

Quizplus · Accepted Answer

The reticular activating system (RAS) is a network of neurons located in the brainstem that plays a crucial role in regulating overall level of consciousness/arousal. Damage to the RAS can result in a state of unconsciousness or coma. The other options listed (corpus callosum, white matter, and medulla oblongata) are also important structures in the brain, but they are not directly involved in regulating overall level of consciousness.
