Single-Neuron Critical Intermittency in a Stochastic Hodgkin-Huxley Model.
Article in The European journal of neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Brain criticality has emerged as a rapidly growing focus of research among neuroscientists and physicists. The latest experimental evidence suggests that even isolated neurons display signs of criticality. Using a stochastic type-I parametrization of the Hodgkin-Huxley model, we investigate the origin of these critical dynamics. We show that the model adequately approximates the experimentally observed behavior, as it reproduces the qualitative relationship between the critical state and both the applied external stimulation and the spiking rate. External white noise further enhances any pre-existing critical intermittency but cannot by itself toggle the system into a critical state. The emergence of the critical state is conditional on the system's proximity to its spiking bifurcation point, and any divergence from it results in the abolition of the dynamics. We treat the neuronal membrane as a complex self-organizing system composed of interacting ion channels and propose that the observed dynamics result from an almost critical state.
