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......阅读全文

开场实验/敞箱实验（Open－field－test）
研究发现，动物在敞箱中，由于对于新异环境的恐惧，主要在敞箱内的周边部活动，而在中央区活动较少，但是动物的探究本性有必然促使它试图在敞箱的中央区活动（包括活动、饮水或进食），从而产生冲突行为。抗焦虑药物在不改变动物一般运动的情况下可以增加实验动物进入敞箱中中央区的次数和中央区停留时间，或者增加实验动物
