Abstract: Microsleeps, the seconds-long interruptions of wakefulness by eye closure and sleep-related brain activity, are dangerous when driving and might be too short to provide the restorative functions of sleep. If microsleeps do fulfill sleep functions, then animals faced with a continuous need for vigilance might resort to this sleep strategy. We investigated electroencephalographically defined sleep in wild chinstrap penguins, at sea and while nesting in Antarctica, constantly exposed to an egg predator and aggression from other penguins. The penguins nodded off >10,000 times per day, engaging in bouts of bihemispheric and unihemispheric slow-wave sleep lasting on average only 4 seconds, but resulting in the accumulation of >11 hours of sleep for each hemisphere. The investment in microsleeps by successfully breeding penguins suggests that the benefits of sleep can accrue incrementally. 2023-01-01T00:00:00Z https://repository.kopri.re.kr/handle/201206/13188 Title: A Study on Monitoring of Antarctic Special Protected Area and Environmental Management of Antarctic Station Authors: Chung, Hosung 2020-06-30T00:00:00Z https://repository.kopri.re.kr/handle/201206/11344 Title: Learning from Life: Getting to Know Authors: Lee, Won Young Abstract: 생명에게 배운다 : 알아간다는 것 2020-03-01T00:00:00Z https://repository.kopri.re.kr/handle/201206/11345 Title: Penguins Go the Way of Penguins.
