AxolotlProtocol:TransplantationoftheGillOrganField
Objective:The overall objective of this laboratory experiment is to examine specification in the axolotl through transplantation of the gill organ field.Introduction:The axolotl (Ambystoma mexicanum) is a large salamander which is native to Lake Xochimilco, Mexico. The axolotl is a member of a larger group of salamanders known as mole salamanders. Other members of this group include tiger salamanders and spotted sala......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
