1 · What the graph read from it

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.

2 · The registry

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

Capturing the intricate dynamics of neural activity in freely behaving animals is essential for understanding the neural mechanisms underpinning specific behaviors. Miniaturized microscopy enables investigators to track population activity at the cellular level, but the field of view (FOV) of these microscopes has often been limited and do not support multi-brain region imaging. To fill this technological gap, we have developed the eXtra Large FOV Miniscope (MiniXL) for mice, a 3.5-gram miniaturized microscope with an FOV measuring 3.5 mm in diameter. We demonstrate the capabilities of the MiniXL through large-scale neuronal population records in hippocampal dorsal CA1. We also demonstrate simultaneous multi-brain region imaging across bilateral medial prefrontal cortex (mPFC) and mPFC and nucleus accumbens (NAc) during complex social behavior and stably track cells across multiple days. As with all microscopes in the UCLA Miniscope ecosystem, the MiniXL is fully open-source and designed to be shared with the neuroscience community to lower the barriers for adoption of this technology.
