Using computational modelling and human single-neuron recordings, we show that the more precisely hippocampal spiking variability tracks the composite features that comprise each individual stimulus, the better those stimuli are later remembered. We propose that moment-to-moment spiking variability may provide a new window into how the hippocampus constructs memories from the building blocks of our sensory world.Competing Interest StatementThe authors have declared no competing interest.
