Modulation of vigilance/alertness using beta (30 Hz) transcranial alternating current stimulation.

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
Vigilance refers to the ability to maintain alertness and sustain attention for prolonged periods to detect and respond to subtle changes in the environment. Previous research has explored the use of transcranial alternating current stimulation (tACS) to modulate brain oscillations and enhance vigilance/alertness. In this study, we explore the modulation effects of different stimulation parameters on Vigilance using an open-source dataset. The open-source dataset includes within participant application of High-Definition tES (HD-tES) types, targeting two cortical regions (frontal, motor) with one stimulation waveforms (30 Hz); combining human-participant high-density electroencephalography (EEG) with continuous behavioral metrics. We only analyzed the behavioral task performance data to assess how vigilant states are acutely altered by specific tES types. Our findings indicate that (1) Both online and offline tACS improve vigilance performance; (2) online tACS have greater effect on vigilance performance than offline tACS; (3) tACS that targeting frontal region have greater effect on vigilance performance than stimulating the motor region. These results align with the view of current the theoretical accounts on the oscillatory nature of vigilance attention and contribute to the groundwork for tACS closed-loop interventions for counteracting vigilance decrements.
