Replay without sharp wave ripples in a spatial memory task.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sharp-wave ripples and hippocampal replay are widely viewed as inseparable components of episodic memory consolidation, with ripples broadcasting the episodic content carried by replay sequences. Here, we show that in male rats performing an open-field spatial memory task, replay can occur in the absence of ripples. Replays with and without ripples were organized in virtual space: ripples were confined to discrete "ripple fields," spatially restricted regions defined over the virtual locations depicted during replay and independent of the rat's location. Ripple fields were direction-independent, stable within sessions, and adapted to environmental changes induced by barriers. Ripple fields were matched across animals exposed to the same environment, revealing a conserved spatial code. These results indicate that ripples and replay are distinct but coordinated processes, with ripples selectively tagging a subset of replays linked to learning or novelty. We propose that this coupling enables targeted broadcast of salient experiences for consolidation.
