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

Cognitive maps enable the flexible selection of navigation paths. Acoustic cognitive maps, constructed from the spatial layout of sonar auditory objects, support bat navigation in natural settings; however, the neural building blocks of acoustic maps remain unknown. Here, we demonstrate auditory object representation in the hippocampus of echolocating bats and test the hypothesis that active tracking drives hippocampal auditory object representation. We discovered two distinct populations of hippocampal CA1 neurons, one encoding allocentric object location and another, egocentric object distance. During trials when the bat ceased object tracking, the spatial code degraded. These findings reveal that auditory information alone can drive the construction of cognitive maps of space, with hippocampal auditory object representations activated by the animal's sonar tracking.
