[Abstract]  The delayed-matching-to-place (DMP) dry maze test is a variant of DMP water maze (Steele and Morris, 1999; Faizi et al., 2012) which measures spatial working/episodic-like learning and memory that depends on both hippocampal and cortical functions (Wang and Morris, 2010; Euston et al., 2012). Using this test we can detect normal aging related spatial working memory decline, as well as trauma induced working memory deficits. Furthermore, we recently reported that fractionated whole brain irradiation does not affect working memory in mice (Feng et al., 2016). Here we describe the experimental setup and procedures of this behavioral test. [摘要]  延迟匹配(DMP)干燥迷宫测试是DMP水迷宫(Steele和Morris,1999; Faizi等人,2012)的变体,其测量空间工作/情景样 依赖于海马和皮质功能的学习和记忆(Wang和Morris,2010; Euston等人,2012)。 使用这个测试,我们可以检测到正常老化相关的空间工作记忆衰退,以及创伤引起的工作记忆缺陷。 此外,我们最近报道,分离的全脑照射不影响小鼠的工作记忆(冯等人,2016年)。 在这里我们描述这个行为测试的实验设置和程序。
【背景】参考记忆水迷宫(RMW)最初用于测量大鼠的空间参考记忆。在这个任务中,通过使用水迷宫之外的远端线索,动物被训练成在不透明水域的固定位置找到隐藏的平台(Morris,1981)。多年来,它已经演变成允许探针试验,过度训练,反向学习和按需平台的各种任务(Morris等人,1982; Morris等人,,1990; Spooner等人,1994; Lipp和Wolfer,1998)。后来,莫里斯实验室开发了一个延迟的匹配地点(DMP)水迷宫,需要在不断变化的环境中经常更新,延迟记录逃生地点(Steele和Morris,1999)。 ...
