Anaesthetised Monkeys Wake Up Instantly When Researchers Stimulate Brain Region Linked To Consciousness
By prodding a tiny brain region linked to consciousness, scientists caused anaesthetised monkeys to suddenly become awake and alert. This fascinating result is providing new clues about the brain and how it produces conscious awareness—insights that could potentially lead to therapies for patients trapped in a coma.
