Sharp wave/ripple (SWR, 150-250 Hz) hippocampal events have long been postulated to be involved in memory consolidation. However, more recent work has investigated SWRs that occur during active waking behaviour: findings that suggest that SWRs may also play a role in cell assembly strengthening or spatial working memory. Do such theories of SWR function apply to animal learning? This review discusses how general theories linking SWRs to memory-related function may explain circuit mechanisms related to rodent spatial learning and to the associated stabilization of new cognitive maps.
长期以来,人们一直假定海马体中的尖波/涟漪(SWR,150 - 250赫兹)事件与记忆巩固有关。然而,最近的研究调查了清醒活动行为期间出现的SWR:这些发现表明,SWR可能在细胞集合强化或空间工作记忆中也发挥作用。SWR功能的这些理论是否适用于动物学习?这篇综述讨论了将SWR与记忆相关功能联系起来的一般理论如何解释与啮齿动物空间学习以及新认知地图相关稳定化有关的神经回路机制。
