Did the Neuron evolve twice?

神经元是动物生存的基础，使生物体能够对感觉刺激做出反应，需要不同功能模块的复杂整合。然而，有研究表明，梳状水母可能独立地进化了它们的神经元和神经系统结构。利用单细胞RNA测序的最新进展，以及在我的博士论文中观察到的相关细胞类型的特征是同源基因的共同表达，我将澄清主茎细胞中的神经元是否与双边动物的神经元同源

Neurons are fundamental for survival in animals, enabling organisms respond to sensory stimuli, requires sophisticated integration of different functional modules. However, it has been suggested comb jellies may have independently evolved their neurons and nervous system structure. Using the recent developments of single-cell RNA-sequencing and observations that related cell-types are characterized by the shared expression of orthologous genes in my PhD I will clarify if neurons in ctenophores are homologous to the one in bilaterians
