Reverberation of excitation in living "hippocampal formation-entorhinal cortex" slices from rats. Optical recording.
Article in Neuroscience and behavioral physiology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A vital potential-dependent dye was used to conduct optical recording of the electrical activity of the hippocampal formation in living slices of the rat brain including the hippocampal formation and the entorhinal cortex. These studies showed that single electrical stimuli applied to the entorhinal cortex, subiculum. and dentate gyrus produced responses in which waves of excitation passed across the hippocampal formation sequentially from the dentate gyrus, through CA3, to the CA1 field of the hippocampus. When GABAergic inhibition was partially blocked with picrotoxin, the first wave of excitation was immediately followed by several further waves in all zones of the hippocampal formation, with a constant shift in latency, which increased from the dentate gyrus to CA3 and CA1. Reverberation of excitation in the "hippocampal formation-entorhinal cortex" structure is regarded as the most probable cause for the appearance of these sequences of waves.
