• 中文摘要： 利用掃描式電子顯微鏡觀察大白鼠胚胎（Sprague Dawley）的神經皺襞，胚胎具有8－11體節，相當於Stage 24，在
  其中段的神經皺襞部分已併合形成神經管。在未併合神經皺襞的表皮細胞與神經細胞交接處發現許多有?狀突出的細胞
  ，此細胞的?狀突出為兩側神經皺襞併合前的轉變，以利神經皺襞早期的粘著。

• 英文摘要： The topography of the ectoderm was examined by scanning electron microscopy during neurulationin rat embryos at stage 24 (somites 8-11). A zone of altered cell morphology was observed along the crestof neural folds. This zone was located between the presumptive neural tube and the surface ectoderm andexhibited numerous rounded cell blebs, immediately prior to fusion between the folds. It is suggested thatthe observed surface alterations may reflect a change in the properties of the altered cell which correlatewith initial adhesion between the folds.
