Altered functional connectivity of emotional circuits and default mode network in postpartum women: a resting-state functional magnetic resonance imaging study.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn the postpartum period, postpartum women experience numerous brain structural and functional changes. Functional neuroimaging studies have focused on the responses of the maternal brain to infant stimuli ; however, the connectivity of the maternal brain remains to be explored. We aimed to examine the differences in functional connectivity patterns between postpartum women and nulliparous women.
methodsResting-state functional magnetic resonance imaging data from 38 postpartum women and 25 nulliparous women were used to analyze functional connectivity. Moreover, we also collected Interpersonal Reactivity Index-C scores. The group functional connectivity differences were analyzed by a two-sample T test.
resultsCompared to nulliparous women, postpartum women exhibited increased functional connectivity in regions associated with emotional processes (insula, hippocampus, posterior cingulate gyrus, and medial frontal gyrus), while functional connectivity in the default mode network (inferior parietal lobule and precuneus) decreased significantly.
conclusionThese results suggest that the maternal brain shows altered connectivity patterns, which may reveal the neuroanatomical basis for processing emotional and cognitive information in postpartum women.
