Summary

在精细动作协调的赤字可以平衡木测试与评估。在横梁上的表现是量化,由梁走过的速度和在横梁上滑动鼠标的次数。

Abstract

脑损伤,遗传操作和药物治疗,可以导致小鼠的运动技能的改动。精细动作的协调和平衡,可梁步行试验评估。此测试的目的是为鼠标停留直立步行到一个安全的平台和跨高架窄波束。这个测试需要连续超过3天:2天的培训和测试1天。在横梁上的表现是量化测量的时间,它需要鼠标遍历梁和爪子单的过程中发生的数量。在这里,我们的报告在我们的实验室中使用的协议,并代表从C57BL / 6小鼠的队列结果。这个任务是特别有用的检测,可能不会被其他电机测试,如Rotarod检测到的运动技能和平衡的微妙的赤字。

Protocol

1。这个协议是基于萨斯维尔等。人 (2009年)和卡特等。人 (2001年)。 1米束束装置由一个12毫米的平面或6毫米宽)休息50厘米以上的两极表的顶端。一个黑盒子被放置在梁端的终点。 (胶合板和其他类型的木材为梁,波兰人,和箱可发现在大多数五金商店)。排料从家里笼放置在黑盒子,吸引了鼠标到终点。一个灯(60瓦灯泡)是用来照耀起点以上的光,和作为一个厌恶?…

Discussion

在平衡木上的表现是良好的协调和平衡的一个有益的措施,已经由以前的工作验证。束测试可以检测到在年轻人和老年人的啮齿类动物 2,3,4的电机由于年龄的赤字,中枢神经SYST`病变,遗传和药理操作。小鼠皮层的影响病变往往表现出对侧束5,6滑倒。束测试也被用来区分野生型(WT)和亨廷顿病(HD)的小鼠模型的运动技能,随着时间的推移,并评估治疗 7,8 HD小鼠的改善。…
