A ventral CA1 to nucleus accumbens core engram circuit mediates conditioned place preference for cocaine.
Article in Nature neuroscience, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 97 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
The importance of neuronal ensembles, termed engram cells, in storing and retrieving memory is increasingly being appreciated, but less is known about how these engram cells operate within neural circuits. Here we tagged engram cells in the ventral CA1 region of the hippocampus (vCA1) and the core of the nucleus accumbens (AcbC) during cocaine conditioned place preference (CPP) training and show that the vCA1 engram projects preferentially to the AcbC and that the engram circuit from the vCA1 to the AcbC mediates memory recall. Direct activation of the AcbC engram while suppressing the vCA1 engram is sufficient for cocaine CPP. The AcbC engram primarily consists of D1 medium spiny neurons, but not D2 medium spiny neurons. The preferential synaptic strengthening of the vCA1→AcbC engram circuit evoked by cocaine conditioning mediates the retrieval of cocaine CPP memory. Our data suggest that the vCA1 engram stores specific contextual information, while the AcbC D1 engram and its downstream network store both cocaine reward and associated contextual information, providing a potential mechanism by which cocaine CPP memory is stored.
