Nervous system is one of the key adaptations underlying the evolutionary success of the majority of animal groups. Ctenophores (or comb jellies) are gelatinous marine invertebrates that were probably the first lineage to diverge from the rest of animals. Due to the key phylogenetic position and multiple unique adaptations, the noncentralized nervous system of comb jellies has been in the center of the debate around the origin of the nervous system in the animal kingdom and whether it happened only once or twice. Here, we discuss the latest findings in ctenophore neuroscience and multiple challenges on the way to build a clear evolutionary picture of the origin of the nervous system.
神经系统是大多数动物群体进化成功的关键适应之一。栉水母（或栉水母）是一种凝胶状的海洋无脊椎动物，可能是第一个与其他动物分支的谱系。由于其关键的系统发育位置和多种独特的适应性，栉水母的非中心化神经系统一直是动物王国神经系统起源的争论焦点，即它是否只发生过一次或两次。在这里，我们讨论了栉水母神经科学的最新发现，以及在构建神经系统起源的清晰进化图景的道路上面临的多个挑战。
