This study shows that learning reshapes hippocampal replay dynamics, causing replay to linger near behaviorally significant locations through reduced adaptation and feedback inhibition.

The paper shows that replay events can occur without sharp wave ripples in rats during a spatial memory task, and that ripple fields are spatially organized and stable.

This study shows that dopamine signaling is not required for reward-related replay increases but is necessary for normal replay patterns in familiar environments.

The paper shows that hippocampal replay during immobility is dominated by self-avoidance, with past paths avoided and future paths prioritized, supported by a symmetry-breaking attractor model.

The paper shows that alternating hippocampal theta sequences emerge in a simple 2D adaptation model and corroborates this with rat navigation data.

This study uses hidden Markov models to analyze population burst events in hippocampal activity, revealing temporal replay sequences and spatial maps without relying on the place code.
