[英文釋義] A strip of specialized ectoderm flanking each side of the embryonal neural plate,which after the closure of the neural tube,forms a column of isolated cells along the dorsal aspect of the neural tube. Most of the cranial and all of the spinal sensory ganglion cells arise by differentiation of neural crest cells.

"it still requires a definitive experiment, where the developing neural crest cells are marked with dye, the embryo develops and the dye clearly shows up in the electroreceptors, " northcutt said 美國其他一些研究者認為這個發(fā)現(xiàn)非常有意思,但是要想在鯊魚神經(jīng)嵴細胞與電感受器之間建立直接聯(lián)系,還需要進行更多的研究。
Glenn northcutt, a neuroscientist at the university of california, san diego, who was not involved in the study, said the finding was interesting, but that more studies are needed before a direct link between neural crest cells and electroreceptors can be established 美國其他一些研究者認為這個發(fā)現(xiàn)非常有意思,但是要想在鯊魚神經(jīng)嵴細胞與電感受器之間建立直接聯(lián)系,還需要進行更多的研究。這項研究是由美國佛羅里達大學(xué)的馬丁科恩和其
