The collective spiking activity of hippocampal principal cells supports information processing and integration for memory-guided behaviour. This population spiking is temporally structured and reflect behavioural states. That is, hippocampal principal cell spiking is sparsely paced by theta oscillations during active exploration but tightly synchronised by sharp-wave/ripples (SWRs) during sleep/rest. Notably, previous studies have related SWRs to a current sink in the stratum radiatum, reporting CA3 inputs that serve memory consolidation. Here, we explore whether individual SWRs deviate from this general pattern of activities. We start by using Principal Components Analysis to analyse and characterise the currents along the somato-dendritic axis of CA1 principal cells during SWRs. We observe a substantial diversity in single SWR events, involving two distinc current profiles: Radsink ripples with a current sink in the stratum radiatum and LMsink ripples with a current sink in the stratum lacunosum-moleculare. We relate these distinct current profiles to different ripple waveforms and intra-ripple frequencies. We show that single-ripple variability unveils a functional link between individual ripple current profiles and transient modulation of principal cell joint firing. These preliminary observations suggest a role for hippocampal laminar somato-dendritic currents in shaping the activity features and mnemonic functions of SWRs.
