    摘要:

    作为一种高级认知活动,视觉功能减弱是否影响听觉恐惧条件化学习目前还不清楚. 本文以突变体rd/rdcl/cl小鼠为视觉功能减弱组,研究视觉功能减弱是否对听觉巴甫洛夫条件化恐惧反应有影响. 在恐惧条件化、恐惧消退和消除记忆再现阶段记录了僵直行为. 研究结果表明,视觉功能的减弱更有利于小鼠听觉恐惧条件化的建立. 文中讨论了出现此结果的可能神经机制.

    Abstract:

    As advanced cognitive activities, it is poorly understood if visual weakening affects auditory fear conditioning. Here we investigated the responses in auditory Pavlovian fear conditioning, using mutant rd/rd, cl/cl mice as visual weakening group. Freezing behaviors were recorded during fear conditioning, fear extinction, and extinction recall phases. The results indicated that mice with shape vision deprivation are more conducive to auditory fear conditioning. We discuss the possible neuro-mechanism of visual-auditory system interactions.
