The Mind after Midnight: Where Do You Go When You Go to Sleep? [Replay]

Live from a World Science Festival event at the New York University Kimmel Center, Eisner & Lubin Auditorium, Friday, June 3, from 8 P.M. to 9:30 P.M. ET

Join Our Community of Science Lovers!

We spend a third of our lives asleep. Every organism on Earth—from rats to dolphins to fruit flies to microorganisms—relies on sleep for its survival, yet science is still wrestling with a fundamental question: Why does sleep exist? During Shakespeare and Cervantes’ time, sleep was likened to death, with body and mind falling into a deep stillness before resurrecting each new day. In reality, sleep is a flurry of action. Trillions of neurons light up. The endocrine system kicks into overdrive. The bloodstream is flooded with a potent cocktail of critically vital hormones. Such vibrant activity begs the question: Where do we go when we go to sleep? Based on new sleep research, there are tantalizing signposts. Join us in exploring this slumbering journey. We’ll delve into the one-eyed, half-brained sleep of some animals; eavesdrop on dreams to understand their cognitive significance; and investigate extreme and bizarre sleeping behaviors like “sleep sex” and “sleep violence.”

Join us in a discussion with leading researchers who delve into the one-eyed, half-brained sleep of some animals, eavesdrop on dreams to understand their cognitive significance, and investigate extreme and bizarre sleeping behaviors such as "sleep sex" and "sleep violence."

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
