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

backgroundBoth drug and natural reward-seeking have been shown to increase following an extended period of abstinence, a phenomenon termed 'incubation of craving'. Although this phenomenon involves many brain regions, the projections from the prelimbic cortex (PrL) to the nucleus accumbens (NAc) core have been strongly implicated in incubation of cocaine-seeking. However, this circuit has not been investigated in the context of incubation of craving for natural rewards.

methodsMale Long Evans rats were trained to self-administer cocaine or water/saline 6 h/d for 14 days and subsequently entered 1 month of experimenter-imposed abstinence. Rats then underwent an optogenetic stimulation protocol used to induce long term depression in the PrL terminals to the NAc core immediately before beginning an extinction test used to assess incubation of craving.

resultsControl cocaine rats showed heightened drug-seeking on day 30 when compared to day 1 of abstinence, demonstrating incubation of craving. Notably, optogenetic stimulation of the PrL to NAc core pathway blocked this behavior in cocaine rats. In contrast, optogenetic stimulation of the PrL to NAc core pathway induced incubation of craving in water/saline rats.

conclusionsThese findings suggest that neuroadaptations in the PrL to NAc core pathway play opposing roles in the incubation of craving for cocaine versus water.
