Which of the following is NOT an arousal-inducing brain area?

Arousal is sustained by several wake-promoting systems, including norepinephrine from the locus coeruleus, acetylcholine from the PPT/LDT, and serotonin from the dorsal raphe. These regions actively promote alertness and cortical activation. In contrast, the ventrolateral preoptic area is a sleep-promoting region that suppresses arousal by releasing GABA (and galanin) to inhibit the wake-promoting centers. Because it drives sleep, not wakefulness, the ventrolateral pre-optic area is not an arousal-inducing brain area.
