Brain region-specific gain modulation of place cells by VIP neurons.
Article in Nature communications, 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
Gain modulation allows neurons to dynamically adjust their responsiveness to inputs without changing selectivity. While well-characterized in sensory areas, its role in higher-order brain regions governing spatial navigation and memory is unclear. Here, we used all-optical methods in mice performing a spatial task to demonstrate that vasoactive-intestinal peptide (VIP)-expressing neurons selectively control the gain of place cells and other cell types in the retrosplenial cortex (RSC) through disinhibition. Optogenetic manipulation revealed that this disinhibition, while broadly affecting network activity, selectively amplifies in-field place cell activity, improving spatial coding accuracy. In contrast, VIP neurons in the hippocampus have minimal impact on place field gain. Notably, simulations indicate that the benefit of gain modulation for RSC place cells is large compared to hippocampal place cells due to their much higher out-of-field activity and, therefore, lower signal-to-noise ratio. Here, we show an area-specific VIP-mediated gain control, enhancing spatial coding and, potentially, memory formation.
