Influences of photic stress on postsubicular head-directional processing.

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
The stress response serves vital adaptive functions. However, acute stress episodes often negatively impact cognitive processing. Here, we aimed to elucidate whether stress detrimentally affects the head-direction cells of the postsubiculum, which may in turn impair downstream spatial information processing. We recorded neurons in the rats' postsubiculum during a pellet-chasing task during baseline non-stress conditions and after a 30-min acute photic stress exposure. Based on their baseline firing rate, we identified a subpopulation of head-direction cells that drastically decreased its firing rate as a response to stress while preserving their head directionality. The remaining population of head-direction cells as well as other neurons recorded in the postsubiculum were unaffected. The observed altered activity in the subpopulation might be the basis for spatial processing deficits observed following acute stress episodes.
