Neuroimaging Meta-Analysis of Brain Activity Changes in Spaceflight and Ground Analogs

A 22.3 KB document presents a coordinate-based meta-analysis of 15 neuroimaging studies on human brain adaptation to altered gravity. The analysis, authored by Scaramelli Anna and last updated in April 2026, used activation likelihood estimation to identify a convergent, right-lateralized brain network. Findings suggest neuroplastic recalibration of internal models for perception and motor behavior in microgravity.

Use Cases

• Identify convergent brain regions affected by microgravity based on the reported right-lateralized sensorimotor network.
• Study neuroplastic adaptations to altered gravitational signals based on the described recalibration of internal models.
• Validate ground-based analogs for spaceflight research based on the inclusion of such studies in the meta-analysis.
• Investigate the neural basis of spatial orientation and motor coordination disruptions mentioned in the sensory conflict theory.

Strengths

• The analysis synthesizes findings from 15 distinct neuroimaging studies, providing a consolidated view.
• Uses a formal coordinate-based meta-analysis method (activation likelihood estimation) for identifying convergent brain activity.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse and adaptation.

Limitations

• The dataset is a 22.3 KB DOCX document, which is a very small text summary and not the underlying neuroimaging data.
• Row count and column-level documentation are absent; the actual data tables and coordinates must be extracted from the document.
• Description metadata is limited; actual data quality and the full list of included studies require manual inspection after download.
