stimulus
a poorly defined network that extends from the hypothalamus to the medulla, mediates
arousal.
Reticular Activating System (RAS)

🔹Extends from hypothalamus to medulla
🔹Mediates arousal
🔹Optimal arousal state: sensoristasis
🔹Monitors and regulates incoming sensory stimuli, maintaining, enhancing, or inhibiting
cortical arousal
States of Awareness
