Cerebellar Crus II Regulates Recognition and Spatial Memory in Mice.
Article in Molecular neurobiology, 2025. 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
The cerebellar Crus II is implicated in the late stages of Alzheimer's disease (AD), yet its specific roles in memory regulation and therapeutic potential remain unclear. Using in vivo fiber photometry, we observed robust activation of Crus II neurons in healthy mice during recognition memory tasks. Acute chemogenetic inhibition of Crus II neurons impaired recognition and spatial memory in mice. Polysynaptic circuit tracing revealed that Crus II neurons modulate neural activity in the contralateral prelimbic cortex (PrL) via the Crus II-cerebellar lateral nucleus (LN)-ventromedial thalamus/zona incerta (VM/ZI)-PrL pathway. In 5 × FAD mice, β-amyloid (Aβ) plaque deposition in Crus II exhibited age-dependent progression, occurring later and less severely compared to the prefrontal cortex. Chronic activation of Crus II neurons ameliorated recognition and spatial memory deficits in 5 × FAD mice. These findings highlight the cerebellar Crus II as a modulator of cognitive function and a potential therapeutic target for AD.
