The spinal premotor network driving scratching flexor and extensor alternation.
Article in Cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Rhythmic motor behaviors are generated by neural networks termed central pattern generators (CPGs). Although locomotor CPGs have been extensively characterized, it remains unknown how the neuronal populations composing them interact to generate adaptive rhythms in mammals. We explored the cooperation dynamics among the three main populations of ipsilaterally projecting spinal CPG neurons-V1, V2a, and V2b neurons-in scratch reflex rhythmogenesis. Individual ablation of the three neuronal populations reduced the oscillation frequency. Activation of excitatory V2a neurons enhanced the oscillation frequency, while activating inhibitory V1 neurons suppressed movement. Building on these findings, we developed a neuromechanical model made of self-oscillating flexor and extensor modules coupled via inhibition. Rhythm frequency is increased by strong intra-module inhibition and facilitation mechanisms in excitatory neurons and decreased by strong inter-module inhibition. In sum, we describe how genetically identified neuron types and the strengths of their synaptic connections drive scratch rhythmogenesis.
