高架十字迷宫实验是一种用于评估小鼠或大鼠情绪状态和焦虑水平的实验。迷宫呈十字形，其中两臂封闭，两臂开放。动物被放置在迷宫中，记录其在开放臂和封闭臂之间的活动。焦虑水平较高的动物更倾向于待在封闭臂，而焦虑水平较低的动物则更愿意探索开放臂。通过分析动物在不同区域的停留时间，可以推断其情绪状态。高架十字迷宫实验广泛用于药物筛选和行为学模型研究。

The elevated plus maze test is an experiment used to assess the emotional state and anxiety levels of mice or rats. The maze is in the shape of a cross, with two arms closed and two open. The animals were placed in the maze and their movements between the open and closed arms were recorded. Animals with higher anxiety levels were more likely to stay in the closed arm, while animals with lower anxiety levels were more likely to explore the open arm. By analyzing the time an animal spends in different areas, its emotional state can be inferred. The elevated plus maze test is widely used in drug screening and behavioral model research.
