Hippocampal place code plasticity in CA1 requires postsynaptic membrane fusion.
Article in Neuron, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Rapid delivery of glutamate receptors to the postsynaptic membrane via vesicle fusion is a central component of synaptic plasticity. However, it is unknown how this process supports specific neural computations during behavior. To bridge this gap, we combined hippocampal CA1 deletion of the t-SNARE protein Syntaxin3 (Stx3), a component of the postsynaptic membrane fusion machinery, with population in vivo calcium imaging. This approach revealed that Stx3 is necessary for neural responses to novelty and for forming stable representations of rewarded locations. By contrast, CA1 Stx3 is dispensable for maintaining aspects of the neural code that exist presynaptic to CA1, such as representations of context and space. Thus, altering the Stx3-dependent postsynaptic membrane fusion machinery identified computations that specifically require synaptic restructuring via membrane trafficking in CA1 and distinguished them from neural representations that could be inherited from upstream brain regions or learned through other mechanisms.
