Quizplus · Accepted Answer

The reticular formation is a network of neurons in the brainstem involved in regulating arousal and sleep-wake transitions. Stimulation of the reticular formation can lead to changes in the level of consciousness, which suggests that this is the most likely area being stimulated in the rabbit's brain to induce sleep or wakefulness.
