本期封面：一只颏带企鹅（Pygoscelis antarcticus）在照顾一只雏鸟，而它的同伴则在小憩。企鹅在南极洲熙熙攘攘的企鹅群中成功繁殖，通过长达数千秒的微睡眠获得了超过 11 个小时的睡眠时间–这种适应性使它们能够注意捕食者和具有攻击性的邻居。研究结果表明，微睡眠可以实现某些睡眠功能。
A chinstrap penguin (Pygoscelis antarcticus) cares for a chick while its partner catches a quick nap. Penguins successfully breeding in the hustle and bustle of a colony in Antarctica obtain more than 11 hours of sleep through thousands of seconds-long microsleeps—an adaption that enables them to watch for predators and aggressive neighbors. The findings suggest that microsleeps can fulfill some sleep functions.
