Probing the linguistic cerebellum: a qualitative review of the effects of cerebellar neurostimulation on language processing.
Synthesis in Frontiers in psychiatry, 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 cerebellum has historically been underrepresented in language research. However, converging evidence from lesion and neuroimaging studies supports its crucial involvement in phonological and semantic aspects of language processing, highlighting the relevance of cerebro-cerebellar circuits in language-related functions. Likewise, cerebellar neurostimulation has emerged as a promising tool for modulating sensorimotor and higher-order cognitive processes. A systematic search was conducted in PubMed and Web of Science following PRISMA guidelines and the present review synthesizes findings from 30 neurostimulation studies probing the causal role of the cerebellum for language processing. It summarizes transcranial electric and magnetic stimulation studies in neurotypical speakers and readers, and individuals with higher-order language disorders. Special emphasis is placed on studies combining cerebellar stimulation with behavioral interventions to assess the potential of improving language-related outcomes in clinical populations. Collectively, these studies support the role of the right posterolateral cerebellum as a key modulator of language functions, especially meaning-related operations.
