This study is a part of a larger study where we
investigate for the first time ever the possible effects
of gravity transitions on brain connectivity and
morphology. We used voxel-based morphometry (VBM) to
assess anatomical differences throughout the brain in 16
healthy and first-time parabolic flyers. MRI
investigations were carried out before and immediately
after the parabolic flight. Our results suggest that
gravity shifts have an impact on brain morphology and
possibly also connectivity, in regions that are know to
play a pivotal role in the integration of neurosensory
information (vestibular, visual and proprioceptive
info).
