Functional partitioning of sentence processing and emotional prosody in the right perisylvian cortex after perinatal stroke.
Article in Scientific reports, 2024. 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
In healthy adults different language abilities-sentence processing versus emotional prosody-are supported by the left (LH) versus the right hemisphere (RH), respectively. However, after LH stroke in infancy, RH regions often support both abilities with normal outcomes. This finding raises an important question: How does the functional map of RH regions change to support both emotional prosody and also typically left-lateralized language functions after an early LH stroke? Does sentence processing simply become reflected into RH frontotemporal regions and overlap with emotional prosody processing? Or do these functions overlap less than would be expected with simple mirroring? In the current work we used task fMRI to examine precisely how sentence processing and emotional prosody processing are both organized in the intact RH of individuals who suffered a large LH perinatal arterial ischemic stroke (LHPS participants). We evaluated the activation of two fMRI tasks that probed auditory sentence processing and emotional prosody processing, comparing the overlap for these two functions in the RH of individuals with perinatal stroke with the symmetry of these functions in the LH and RH of their healthy siblings. We found less activation overlap in the RH of individuals with LH perinatal stroke than would be expected if both functions retained their typical spatial layout, suggesting that their spatial segregation may be an important feature of a functioning language system.
