EEG Correlates of Auditory Short-Term Memory and Dissimilarity Perception in Young and Older Adults.
Article in The European journal of neuroscience, 2025. 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
Understanding the neural correlates of short-term memory is crucial, particularly in the context of aging. In this electroencephalography (EEG) study, we investigated the impact of aging on the brain activity underlying short-term memory and perception of dissimilarity of auditory sequences. Fifty-four participants were divided into two groups: (i) 29 young adults (20-30 years old) and (ii) 25 older adults (60-80 years old). We used a variation of the same/different task employing pairs of tone sequences and asking participants to rate the degree of dissimilarity of the second sequence in comparison to the first one. Sequences could be either identical (same), totally different, or with transposed tones. Behavioral results showed a lower level of perceived dissimilarity in different sequences in older compared to young adults. The memory task induced a fronto-central negative slow wave (NSW) that was significantly higher in the 20-30 group for all three conditions. NSW was higher in the same than in the different and transposed conditions but only in young adults. In transposed sequences, NSW amplitude was modulated by the perception of dissimilarity. The P50 component to first sound of the second sequence was significantly higher in older adults. The N1 was more negative in the same than in the different and transposed conditions. The P2 was higher in the same than in the transposed condition.
