What changes in microgravity?
Spaceflight produces headward fluid shifts. NASA studies associated brain and eye changes including spaceflight-associated neuro-ocular syndrome.
Why it matters
Research into neurological health can help explain disease burden, human physiology and opportunities for future scientific work. The underlying mechanisms are complex and many questions remain unresolved.
Scientific context
NeuroClearance is interested in questions relevant to this field. No NeuroClearance clinical effect or performance benefit has been demonstrated. These pages describe the science in general terms rather than specific devices or methods.
