Daily Artificial Gravity is Associated with Greater Neural Efficiency during Sensorimotor Adaptation

This study shows that daily artificial gravity reduces brain activation during sensorimotor adaptation compared to head-down tilt bed rest.

The effects of long duration spaceflight on sensorimotor control and cognition

This study examines how long-duration spaceflight affects sensorimotor control and cognition, finding transient declines in mobility, balance, and bimanual coordination that recover within 30 days, while cognitive performance remains stable.

MRI-Visible Perivascular Space (PVS) Changes with Long-Duration Spaceflight

This study examines how spaceflight affects MRI-visible perivascular spaces (PVSs) in astronauts, finding that novice astronauts show increased PVS volume post-flight, while experienced astronauts show baseline correlations between flight days and PVS length.

Ophthalmic Changes in a Spaceflight Analog Are Associated with Brain Functional Reorganization

This study examines resting-state functional connectivity changes in a spaceflight analog, finding distinct patterns in those who develop optic disc edema compared to those who do not.

Brain Connectivity and Behavioral Changes in aSpaceflight Analog Environment with Elevated CO2

This study examines how a spaceflight analog environment with elevated CO2 affects brain connectivity and sensorimotor performance over time.
