Adoption of microfluidic MEA technology for electrophysiology of 3D neuronal networks exposed to suborbital conditions.
Article in NPJ microgravity, 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
Studying neuronal cells in space reveals how microgravity affects brain function, gene expression, and cellular processes. This study details the preparation and validation of a 3D neuronal electrophysiology (EPHYS) sensing microfluidic biodevice used during a suborbital space flight. Initially, the device's function was tested with rat hippocampal neurons using EPHYS data collected via a microelectrode array (MEA). This system was later applied to human glutamatergic (Glu) neurons for eight days preceding a suborbital flight. A live-dead assay confirmed cell viability, and the system was integrated into a CubeLab to maintain a controlled environment. Two biological samples were flown, along with two control samples, to validate the EPHYS system. Results showed that human Glu-neurons exposed to microgravity exhibited altered expression of vesicular glutamate transporters (VGLUTs) while maintaining neuronal differentiation markers. The findings contribute to understanding neurological disorders, neuro-inflammation, and cognitive impacts of space travel, with broader applications for brain health research on Earth.
