Olfactory Cued Learning Paradigm

[Abstract]  Sensory stimulation leads to structural changes within the CNS (Central Nervous System), thus providing the fundamental mechanism for learning and memory. The olfactory circuit offers a unique model for studying experience-dependent plasticity, partly due to a continuous supply of integrating adult born neurons. Our lab has recently implemented an olfactory cued learning paradigm in which specific odor pairs are coupled to either a reward or punishment to study downstream circuit changes. The following protocol outlines the basic set up for our learning paradigm. Here, we describe the equipment setup, programming of software, and method of behavioral training. [摘要]  感觉刺激导致CNS(中枢神经系统)内的结构变化,从而提供学习和记忆的基本机制。 嗅觉电路提供了一个独特的模型,用于研究经验依赖的可塑性,部分原因是连续供应整合成人神经元。 我们的实验室最近实施了一个嗅觉提示学习范例,其中特定的气味对与奖励或惩罚相结合,以研究下游电路的变化。 以下协议概述了我们学习范式的基本设置。 在这里,我们描述设备设置,软件编程和行为训练方法。
【背景】成年大脑具有持续的经验依赖性结构变化。在首先处理气味信息的啮齿动物嗅球(OB)中,连续供应成年出生的中间神经元(颗粒细胞)或者整合到嗅觉电路中或经历凋亡(Petreanu和Alvarez-Buylla,2002; Carleton等,2003 ; Lledo等人,2006; Sakamoto等人,2014)。生存或死亡之间的选择受感觉刺激和嗅觉提示学习的影响很大(Rochefort等,2002; Alonso等,2006)。此外,较小的颗粒细胞在关键时间窗内也经历依赖于经验的突触变化(Yamaguchi and Mori,2005)。为了研究感觉体验如何影响OB电路中的突触可塑性,我们的实验室已经成功实施了Go / No-Go嗅觉学习任务(Huang et al。,2016; Quast et ...
