Ventricular volume increases depended on duration in flight, type of space flight, and astronaut age (A–C). Note that the following modifications were made to the figures to protect astronaut anonymity: Individual data points for mission duration and ISS astronaut ages are not plotted. Instead, the regression line and 95% confidence bands are shown. A, Boxplot showing %ΔVV versus mission duration. B, %ΔVV versus mission duration, including Shuttle and ISS astronauts. C, %ΔVV versus ISS astronaut age at launch.

Spaceflight results in crowding of brain tissue at the vertex. Red voxels indicate regions along the brain surface where there was an increase in brain parenchyma pre- to postflight due to crowding of the brain tissue as the brain shifted upwards. Blue voxels indicate displaced brain tissue that occurred predominantly along the margins of the lateral and third ventricles due to enlargement of the ventricles postflight.

Regional deformation of brain parenchyma that significantly predicted performance on motor function tests. A, Regional deformation of brain parenchyma that significantly predicted performance on the Recovery from Fall/Stand Test (P < .05). B, Regional deformation of brain parenchyma that significantly predicted performance on the Dynamic Postural Stability Test (P < .05). C, Regional deformation of brain parenchyma that significantly predicted performance on the Seated Egress and Walk Test (P < .05).
- Fig 4.
Regional deformation of brain parenchyma that significantly predicted performance on the Continuous Performance Test (P < .05).
