The effects of corticotropin-releasing factor on motor learning.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Corticotropin-releasing factor (CRF) is mainly secreted from the hypothalamic paraventricular nuclei and plays a crucial role in stress-related responses. Recent studies have reported that CRF is a neuromodulator in the central nervous system. In the cerebellum, CRF is essential for the induction of long-term depression (LTD) at the parallel fiber-Purkinje cell synapses. Given that LTD is thought to be one of the fundamental mechanisms of motor learning, CRF may affect motor learning. However, the role of CRF in motor learning in vivo remains unclear. In this study, we aimed to examine the role of CRF in motor learning. This was achieved through a series of behavioral experiments involving the in vivo administration of CRF and its antagonists. Rats injected with CRF directly into the cerebellum exhibited superior performance on the rotarod test, especially during initial training phases, compared to control subjects. Conversely, rats receiving a CRF receptor antagonist demonstrated reduced endurance on the rotating rod compared to controls. Notably, CRF mRNA expression levels in the cerebellum did not show significant variance between the CRF-injected and control groups. These findings imply a critical role of endogenous CRF in cerebellar motor learning and suggest that exogenous CRF can augment this process. (199 words).
