Simultaneous awake replay of multiple spatial representations.
Article in Neuron, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
How the hippocampus processes multiple spatial memories during awake decision-making remains unclear. Using a rat observational navigation task, we tested whether distinct spatial representations are replayed simultaneously during sharp-wave ripple-associated population bursts. Place cell sequences representing multiple T-maze trajectories were frequently replayed together during reward consumption and were particularly prominent in the observation box. These simultaneous replay events reflected the spatial organization of the maze, preferentially converged on reward sites, distinguished future behavioral choices, and were associated with choice-selective activity in anterior cingulate cortex. Replay of a single trajectory showed weaker relationships to behavior and cortical activity. These findings establish simultaneous awake replay of multiple spatial representations and support a role for parallel hippocampal processing during reward-directed observational navigation.
