Researchers at the University of Antwerp said they found “significant” microstructural changes in several white matter tracts.
The human brain can change and adapt in structure and function throughout a lifespan. As human exploration of space reaches new horizons, understanding the effects of spaceflight on human brains is crucial.
Previous research has shown that spaceflight has the potential to alter both the shape and function of an adult brain.
White matter refers to the parts of the brain that are responsible for communication between grey matter and the body, and between various grey matter regions.
To study brain structure and function after spaceflight, the researchers used a brain imaging technique called fibre tractography.
“Fibre tractography gives a sort of wiring scheme of the brain. Our study is the first to use this specific method to detect changes in brain structure after spaceflight,” explained team leader Dr Floris Wuyts.
The team acquired...
