Spatially global effects of feature-based attention in functional subdivisions of human subcortical nuclei.

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
Attention can prioritize the processing of non-spatial features throughout the visual field, yet the neural mechanisms of feature-based attention in subcortical regions remain poorly understood. Using high-resolution functional magnetic resonance imaging (fMRI) at 7 T, we investigated the global effects of color-based attention in functional subdivisions of human subcortical nuclei. Color-based attention selectively enhanced activity in the parvocellular layers of the lateral geniculate nucleus of the thalamus for unattended stimuli across the visual field, while reducing responses to attended stimuli. Both feedforward and feedback connectivity with the primary visual cortex were enhanced. In addition, our results suggest that the deeper layers of the superior colliculus contribute to attentional control of this spatially global effect, while the ventral pulvinar coordinates connectivity between visual areas. Together, these findings uncover a global attention mechanism in the visual thalamus and reveal the distinct roles of subcortical nuclei in feature-based attention.
