Brains of cosmonauts get 'rewired' to adapt to long-term space missions, study finds

A new study published in Frontiers in Neural Circuits is the first to analyze the structural connectivity changes that happen in the brain after long-duration spaceflight. The results show significant microstructural changes in several white matter tracts such as the sensorimotor tracts. The study can form a basis for future research into the full scope of brain changes during human space exploration.
