Although sleep is a very conspicuous behavior in all animals that we are frequently in contact with and possibly in many others, its scientific study was for many years restricted to very few of them. However, since the end of the XX century there have been studies about sleep in several animals and currently many of them attempt to found, first, if all animals sleep and second, if their sleep is similar to that of other animals. An important objective of this search is to identify the animal species in which sleep originated, which might gives us clues about the need that was fulfilled by such behavior. The search started with insects, among the most developed arthropods, but has now been expanded to include other invertebrates, among them crustaceans. In this work we review some aspects of sleep in invertebrates, focusing on the crustacean crayfish, animals in which both, behavioral and electrophysiological studies have been conducted and whose results show surprising similarities with sleep in mammals.
尽管睡眠在我们经常接触的所有动物以及可能在许多其他动物中都是一种非常明显的行为,但其科学研究多年来仅限于极少数动物。然而,自20世纪末以来,已经有关于多种动物睡眠的研究,目前许多研究首先试图确定是否所有动物都睡眠,其次它们的睡眠是否与其他动物的睡眠相似。这种探索的一个重要目标是确定睡眠起源于哪种动物物种,这可能会为我们提供关于这种行为所满足的需求的线索。探索始于昆虫,它们是最发达的节肢动物之一,但现在已经扩展到包括其他无脊椎动物,其中有甲壳类动物。在这项工作中,我们回顾了无脊椎动物睡眠的一些方面,重点是甲壳类动物小龙虾,在这种动物中已经进行了行为和电生理研究,其结果显示出与哺乳动物睡眠惊人的相似之处。
