Stimulating the Stimulated Cortex-Frontocortical Anodal Electric Stimulation Combined With Closed-Loop Acoustic Stimulation During Sleep Impairs Memory in Subjects With High Cognitive Ability.
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
This study investigates the impact of simultaneous anodal transcranial direct-current stimulation (tDCS) and closed-loop acoustic stimulation (CLAS) during slow-wave sleep on memory consolidation and neural oscillations. In this experiment, anodal tDCS was used to modulate cortical excitability, aiming to alter the brain state and investigate the resultant impact of CLAS-induced effects on sleep electroencephalography and overnight memory consolidation. Twenty participants (aged 18-30) completed two experimental nights involving either CLAS alone or tDCS combined with CLAS (AmodCLAS). Offline detected spontaneous SOs were shifted toward negative potential values by AmodCLAS, SO duration was increased, and density decreased. AmodCLAS also decreased sleep efficiency and REM sleep in the second part of the night. Compared with CLAS alone, AmodCLAS failed to influence memory consolidation across all subjects. However, memory retention of participants with higher fluid intelligence (as measured by Raven's Advanced Progressive Matrices) was significantly decreased after AmodCLAS, together with a more pronounced negative shift of SO up-state intervals, yet a weaker reduction in REM sleep. Our findings suggest that individuals with higher cognitive ability exhibit greater susceptibility to sleep-based neuromodulation while possibly possessing greater resilience against sleep perturbance. This highlights the critical role of interindividual cognitive differences in shaping responsiveness to neuromodulation techniques and underscores the need for personalized approaches during such interventions.
