DevelopmentoftheHeartMorphogeneticFieldintheAxolotlEmbryo
IntroductionThere are two modes of development common to most species in the animal kingdom.Virtually all embryos undergo both mosaic and regulative development at some point during their growth. Regulative development generally occurs in early gastrulation when cells are induced to form different structures according to the cell-cell signaling interactions in a specific area of the embryo that lead to the conditiona......閱讀全文

開場實驗/敞箱實驗（Open－field－test）
研究發現，動物在敞箱中，由于對于新異環境的恐懼，主要在敞箱內的周邊部活動，而在中央區活動較少，但是動物的探究本性有必然促使它試圖在敞箱的中央區活動（包括活動、飲水或進食），從而產生沖突行為。抗焦慮藥物在不改變動物一般運動的情況下可以增加實驗動物進入敞箱中中央區的次數和中央區停留時間，或者增加實驗動物
