Activation of 5-HT7 receptor by administration of its selective agonist, LP-211, modifies explorative-curiosity behavior in rats in two paradigms which differ in visuospatial parameters.
Article in CNS neuroscience & therapeutics, 2018. 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
aimsThe serotonin 7 receptor (5-HT7R) subtype, coded by Htr7 gene, is broadly expressed in the central nervous system (CNS) with clear involvement in behavioral functions such as learning/memory, regulation of mood, and circadian rhythms. In this study, we assessed effects of 5-HT7R stimulation by administration of its selective agonist, LP-211 (0.25 mg/kg i.p.), in adult Wistar-Han rats.
methodsWe used two different explorative-curiosity tests. Drug was administered either before one side-chamber familiarization (CF/V group) or immediately after it, to act on consolidation of familiarization (V/CF group).
resultsExp. 1 for novelty seeking in black/white boxes (BWB), with door opening after 5 minutes in the familiar chamber, showed that (i) time spent in the novel environment (significantly higher than in familiar chamber for controls) is enhanced in V/CF group (potentiated recognition for a "visual" consolidation) and not different in CF/V group; (ii) activity and chamber transitions, made by CF/V rats, are significantly higher than for other groups (interference on recognition for a "spatial" acquisition). Exp. 2 for novelty preference in D- vs L-shaped chambers (D/L), with start from neutral center, gave different results: (i) time spent in the novel environment by CF/V group is significantly higher than other groups (potentiated "cognitive" acquisition); (ii) chamber transitions made by V/CF group are significantly higher than other groups (potentiated "emotional" consolidation).
conclusionThese apparently conflicting results may reflect LP-211 effects on visual vs spatial memory (D/L apparatus has more pronounced hippocampal components than BWB). However, further experiments are needed to analyze more in depth the mechanisms involved.
