Decoding P300 as a shared neural mechanism for oddball target detection and working memory updating.
Article in iScience, 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
The P300 is a well-established neurophysiological component that has been extensively investigated within the oddball paradigm and is commonly interpreted as reflecting context or working memory (WM) updating. This interpretation implies that the P300 elicited by oddball target detection shares neural mechanisms with the P300 elicited by WM. To test this hypothesis, we applied multivariate pattern analysis to perform cross-task decoding between EEG patterns during an oddball task and an n-back task, a classical WM paradigm. We found that classifiers trained on EEG patterns from the oddball task successfully decoded those from the n-back task, and vice versa, with the effect concentrated in the parietal/occipital region within the P300 time window. These findings suggest that the P300 serves as a shared neural mechanism for oddball target detection and WM updating, supporting the WM updating account of the P300 from the perspective of neural representation.
