The basal ganglia and the epilepsies.
Review in Epilepsia open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 basal ganglia are an evolutionarily conserved neural circuit best known for the selection and sequencing of voluntary movement. Increasing evidence, however, indicates that these structures also play an important role in regulating pathological brain states, including seizures. Early pharmacological and lesion studies demonstrated that manipulation of basal ganglia output nuclei, particularly the substantia nigra pars reticulata, profoundly alters seizure susceptibility across multiple experimental models. Subsequent work expanded this view, revealing that several basal ganglia structures, including the striatum, subthalamic nucleus, globus pallidus, and superior colliculus, participate in a distributed network capable of modulating seizure initiation, propagation, and generalization. Modern systems neuroscience approaches have begun to define the specific cell types and projection-defined pathways through which these effects are mediated. Together, these findings support the concept that the basal ganglia function as a "seizure-gating" network that interacts with thalamocortical and brainstem arousal systems to regulate cortical synchronization. Understanding how these circuits influence seizure dynamics may enable new therapeutic strategies that strengthen endogenous seizure-suppressing networks rather than targeting the seizure focus alone. PLAIN LANGUAGE SUMMARY: The basal ganglia are a group of deep brain structures best known for helping to start and stop movements. Over the past 40 years, research has shown that they also act as a brake on seizures. Studies across species demonstrate that "turning off" one of the main output structures of the basal ganglia, the substantia nigra pars reticulata, can stop many types of seizures. This review presents the "wiring diagram" of this brain circuit, including the effects of "turning on" and "turning off" individual brain regions and their connections on seizure initiation, propagation, and termination.
