Increase in serotonin precursor levels reinstates the context memory during reconsolidation.

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
In the present study, we tested possible ways of modification of the context long-term memory using the reconsolidation as a tool. Recently, using a depletion of the serotonin content, it was shown that the reinforcing neurotransmitter serotonin is necessary for successful repeated reconsolidation of context memory in terrestrial snails Helix lucorum (Balaban et al. in Sci Rep 6:36933, 2016), and in the present study, we investigated effects of serotonin increase in memory maintenance by injection of the serotonin precursor 5-hydroxytryptophan (5-HTP). We studied reinstatement of the context memory after its impairment during reconsolidation with a protein synthesis blocker anisomycin (ANI) or with a specific inhibitor of protein-kinase Mζ (ZIP). It was observed that applications of 5-HTP alone, known to increase the release of serotonin, or reactivation of memory alone did not restore the ZIP- or ANI-impaired context memory, while combination of the 5-HTP + reactivation of memory effectively reinstated the context memory. The data obtained confirmed the assumption that serotonin/reinforcing transmitter is a part of successful reconsolidation necessary for memory maintenance, demonstrated possible ways of long-term memory regulation during the reconsolidation process.
