The hippocampus is a crucial brain region involved in the process of forming and consolidating memories. Memories are consolidated in the brain through synaptic plasticity, and a key mechanism underlying this process is called long-term potentiation (LTP). Recent research has shown that cholecystokinin (CCK) plays a role in facilitating the formation of LTP, as well as learning and memory consolidation. However, the specific mechanisms by which CCK is involved in hippocampal neuroplasticity and memory formation are complicated or poorly understood. This literature review aims to explore the role of LTP in memory formation, particularly in relation to hippocampal memory, and to discuss the implications of CCK and its receptors in the formation of hippocampal memories. Additionally, we will examine the circuitry of CCK in the hippocampus and propose potential CCK-dependent mechanisms of synaptic plasticity that contribute to memory formation.
海马体是一个参与形成和巩固记忆的关键脑区。记忆是通过突触可塑性在大脑中巩固的,而这个过程的一个关键机制被称为长时程增强(LTP)。最近的研究表明,胆囊收缩素(CCK)在促进 LTP 的形成以及学习和记忆的巩固中起着作用。然而,CCK 参与海马体神经可塑性和记忆形成的具体机制还很复杂或尚未完全理解。这篇文献综述旨在探讨 LTP 在记忆形成中的作用,特别是与海马体记忆的关系,并讨论 CCK 及其受体在海马体记忆形成中的意义。此外,我们将研究 CCK 在海马体中的回路,并提出可能的依赖 CCK 的突触可塑性机制,这些机制有助于记忆的形成。
