Neural events are characteristic transient, coordinated neural activities observable in the brain’s aggregate signals, such as local field potentials (LFPs). It was shown that certain neural events, like sharp wave-ripples (SWR) [1], play a crucial role in various cognitive functions, including memory consolidation and both offline and online planning. These events have signatures across nearly all scales, from microscopic coordination at the level of individual spiking activity and synaptic dynamics [2] to macroscopic regulation in the thalamocortical system [3]. Despite the growing recogniti
