Electrical stimulation of the reticular formation would most likely cause an animal to:

  • A. sneeze
  • B. become blind
  • C. wake up if it had been sleeping
  • D. stop breathing
Correct Answer: C

Rationale: The reticular formation is a network of neurons located in the brainstem that plays a key role in regulating arousal and consciousness. Electrical stimulation of this area can activate the ascending reticular activating system (ARAS), which promotes wakefulness and alertness. This is why stimulating the reticular formation would most likely cause a sleeping animal to wake up. The reticular formation also helps filter sensory information and maintain attention.
