This study investigates how adult born granule cells influence pattern separation by modulating remapping of place and cue cells in the hippocampus.

The paper introduces E-Cannula, a tool for simultaneous electrical and optical recording in the hippocampus, revealing anatomical diversity in sharp-wave ripples and their association with distinct cell assemblies.

The paper identifies two distinct spiking modes in forebrain neurons: a universal ground state and context-dependent activated state, with implications for neuronal function.

The paper identifies 'cue cells' in the dentate gyrus that encode sensory cues independently of spatial location, alongside traditional 'place cells', revealing a previously overlooked heterogeneity in DG function.

The paper shows that offline memory reactivation stabilizes long-term spatial representations by counteracting reward-related biases, promoting comprehensive cognitive maps.

The paper introduces a zero-inflated gamma model for deconvolved calcium imaging traces, showing it outperforms simpler models in simulated and real neural data.
