When rats are placed in a novel environment, they alternate between progression and stopping: in the course of a session they stop briefly in many places, but in one or two places they also stop for very long periods. The place in which they stay for the longest cumulative time is defined as the rat's home base. In this place the incidences of grooming and of rearing are high and often the highest. In addition, the number of visits to the home base is typically the highest. Some rats establish a secondary base with similar properties to those of the main home base. The location of the base influences the mode of progression throughout the environment: progression away from base is slower and includes more stops than progression back. It is suggested that this paradigm may be used for the analysis of the spatial organization of locomotor behavior in neuroscience research.
当把大鼠置于一个新环境中时，它们会在前进和停顿之间交替：在一次实验过程中，它们会在许多地方短暂停顿，但在一两个地方也会长时间停留。它们停留累计时间最长的地方被定义为大鼠的家基地。在这个地方，梳理毛发和直立的发生率很高，而且往往是最高的。此外，对家基地的访问次数通常也是最高的。一些大鼠会建立一个与主要家基地性质相似的次级基地。基地的位置会影响在整个环境中的前进方式：远离基地的前进速度较慢，且比返回时包含更多的停顿。有人认为，这种范式可用于神经科学研究中运动行为空间组织的分析。
