Oxytocinergic projection from the hypothalamus to supramammillary nucleus drives recognition memory in mice.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Oxytocin (OXT) neurons project to various brain regions and its receptor expression is widely distributed. Although it has been reported that OXT administration affects cognitive function, it is unclear how endogenous OXT plays roles in cognitive function. The present study examined the role of endogenous OXT in mice cognitive function. OXT neurons were specifically activated by OXT neuron-specific excitatory Designer Receptors Exclusively Activated by Designer Drug expression system and following administration of clozapine-N-oxide (CNO). Object recognition memory was assessed with the novel object recognition task (NORT). Moreover, we observed the expression of c-Fos via immunohistochemical staining to confirm neuronal activity. In NORT, the novel object exploration time percentage significantly increased in CNO-treated mice. CNO-treated mice showed a significant increase in the number of c-Fos-positive cells in the supramammillary nucleus (SuM). In addition, we found that the OXT-positive fibers from paraventricular hypothalamic nucleus (PVN) were identified in the SuM. Furthermore, mice injected locally with CNO into the SuM to activate OXTergic axons projecting from the PVN to the SuM showed significantly increased percentage time of novel object exploration. Taken together, we proposed that object recognition memory in mice could be modulated by OXT neurons in the PVN projecting to the SuM.
