Table 2_The human brain in space: a meta-analysis of neuroimaging evidence.docx

A coordinate-based meta-analysis of 15 neuroimaging studies identifies convergent brain activity patterns altered by spaceflight and ground-based analogs. The analysis, performed using activation likelihood estimation (ALE), reveals a right-lateralized network centered on sensorimotor cortices and the insula. This 44.6 KB document, authored by Scaramelli Anna and licensed under CC-BY-4.0, was last updated in April 2026.

Use Cases

• Identify neural correlates of gravitational adaptation based on the reported convergent activity in sensorimotor and insular regions.
• Validate ground-based microgravity analog models by comparing their neuroimaging signatures to those from spaceflight studies mentioned in the meta-analysis.
• Investigate the lateralization of brain function in extreme environments based on the finding of a predominantly right-lateralized network.
• Study neuroplastic changes in internal models for perception and motor control based on the discussion of recalibration mechanisms.

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) to identify statistically convergent brain activity.
• The document is openly shared under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• The dataset is a 44.6 KB DOCX file, indicating a very limited scope, likely containing only the analysis text and results tables.
• Row count and column-level documentation are unknown, which may limit suitability assessment for direct computational analysis.
• The underlying neuroimaging data from the 15 source studies is not included, only the meta-analysis results.
