1 · What the graph read from it

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.

2 · The registry

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

Periodic sensory stimuli are prevalent in natural environment and may signal events of particular importance. However, whether periodic and aperiodic stimuli are differentially processed by neural circuits remains unclear. Here we show that periodic stimuli exert influences over longer distances than aperiodic stimuli at both neuronal and perceptual levels. Whole-cell recording from rat visual cortex showed that periodic visual stimulation (1-11 Hz) outside the neuronal receptive field evoked robust membrane potential oscillation at the stimulation frequency, while the same stimulus applied aperiodically had little effect. Human psychophysical experiments showed that periodic luminance changes in the distant surround also exert a stronger modulation of perceived brightness of a centre test stimulus than that exerted by aperiodic changes. Furthermore, both perceptual and neuronal modulation increased with the number of stimulation cycles for periodic surround stimuli. Thus, periodic stimuli can modulate both cortical responses and visual perception over larger spatial scales, generating more global impact on cortical information processing.
