1 · What the graph read from it

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.

2 · The registry

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

A widely accepted notion for a process underlying memory formation is that learning changes the efficacy of synapses by the mechanism of synaptic plasticity. While there is compelling evidence of changes in synaptic efficacy observed after learning, demonstration of persistent synaptic changes accompanying memory has been elusive. We report that acquisition of a hippocampus and long-term potentiation dependent place memory persistently changes the function of CA1 synapses. Using extracellular recordings we measured CA3-CA1 and EC-CA1 synaptic responses and found robust changes in the CA3-CA1 pathway after memory training. Crucially, these changes in synaptic function lasted at least a month and coincided with the persistence of long-term place memories; the changes were only observed in animals that expressed robust memory, and not in animals with poor memory recall. Interestingly, our findings were observed at the level of populations of synapses; suggesting that memory formation recruits widespread synaptic circuits and persistently reorganizes their function to store information.
