The Circadian Arousal System is also known as

• awake

The Circadian Arousal System ("Process C") is made up of:

This opposing and powerful army is called:

• Homeostatic Sleep Drive

• The Circadian Arousal System

• The Central Nervous System

The Homeostatic Sleep Drive is also known as:

• Process S

• Process H
