Meredith:我经常观察我的三条腿的狗Houdini在睡觉时抽动,这让我好奇它是否在梦中拥有四条腿。我认为动物的抽动可能与梦境有关,因为快速眼动睡眠期间的抽动和眼动通常被认为是梦境的体现。 Mark Blumberg:最初我也认为抽动与梦境有关,但后来我注意到新生动物也会抽动,这让我开始怀疑。如果抽动真的与梦境有关,那么经验越丰富,抽动应该越多,但事实并非如此。我认为对梦境的过度关注分散了我们对睡眠真正重要方面的注意力。通过实验,我发现切断新生鼠大脑中负责梦境的部分,它们的抽动仍然正常,这表明抽动并非由梦境引起。我认为抽动可能具有我们尚未探索的内在价值。 Noam Hassenfeld:Mark的研究挑战了我们对睡眠抽动的传统理解,并促使我们重新思考大脑和身体之间的关系。他的研究表明,睡眠抽动可能不仅仅是梦境的副产品,而是一个重要的发育过程。

Chapters
The episode starts by discussing sleep twitches, specifically in animals. It questions whether these twitches are related to dreams, introducing the main topic of the podcast.
  • Sleep twitches, or myoclonic jerks, are observed in humans and animals.
  • These twitches occur during REM sleep, the stage associated with dreaming.
  • There's a long-held belief that these twitches reflect dream activity.
