[Abstract]  Determining the neuronal circuitry responsible for specific behaviors is a major focus in the field of neurobiology. Activity-dependent immediate early genes (IEGs), transcribed and translated shortly after neurons discharge action potentials, have been used extensively to either identify or gain genetic access to neurons and brain regions involved in such behaviors. By using immunohistochemistry for the protein product of the IEG c-Fos combined with retrograde labeling of specific neuronal populations, precise experimental timing, and identical data acquisition and processing, we present a method to quantitatively identify specific neuronal subpopulations that were active during social encounters. We have previously used this method to show a stronger recruitment of ventral hippocampal ... [摘要]  [摘要] 确定负责特定行为的神经元回路是神经生物学领域的主要重点。在神经元释放动作电位后不久就转录和翻译的依赖活动的立即早期基因(IEG)已被广泛用于识别或获得涉及此类行为的神经元和大脑区域的遗传途径。通过对IEG c- Fos 的蛋白质产物使用免疫组织化学,结合特定神经元群体的逆向标记,精确的实验时间,相同的数据采集和处理 ng,我们提出了一种方法,可以定量地识别在社交活动中活跃的特定神经元亚群。与社交活动后投射到下丘脑外侧的神经海马神经元相比,我们以前曾使用这种方法显示出投射到内侧前额叶皮层的腹侧海马神经元更强的募集。在优化用于逆行示踪剂注射的手术后,该方法将有助于识别和定位参与许多不同行为的神经元群体。

[背景] 神经生物学领域的基本目标是确定大脑如何处理感觉输入并产生行为输出命令。在过去的二十年中,某些大脑区域已成为控制特定行为的典范实例,例如海马体用于位置记忆(Bird和Burgess,2008年)。最近的工作开始以可以推广到多种行为的方式来解析这些区域的特定功能(Aronov 等人,2017),并确定在由远程神经元连接的给定行为中多个大脑区域的作用投影( ...
