Understanding the memory substrates underlying substance abuse requires the permanent tagging and manipulation of drug-recruited neural ensembles. Here, we present a protocol for activity-dependent labeling and chemogenetic manipulation of fentanyl-activated striatal ensembles using the ArcTRAP approach. We outline the necessary steps to breed ArcTRAP mice, prepare drugs and reagents, conduct behavioral training, and perform tagging and manipulation. This approach can be adapted to investigate drug-recruited ensembles in other brain regions, providing a versatile tool for exploring the neural mechanisms underlying addiction. For complete details on the use and execution of this protocol, please refer to Wang et al..
理解物质滥用的记忆基质需要对药物招募的神经集合进行永久标记和操作。在这里,我们使用 ArcTRAP 方法介绍了一种用于芬太尼激活的纹状体集合的活性依赖性标记和化学遗传操作的方案。我们概述了繁殖 ArcTRAP 小鼠、准备药物和试剂、进行行为训练以及进行标记和操作所需的步骤。这种方法可以适应于研究其他脑区的药物招募集合,为探索成瘾的神经机制提供了一种通用工具。有关此方案的使用和执行的完整详细信息,请参阅 Wang 等人的研究。
