Changes in brain structure and function may play a direct role in spaceflight-associated sensorimotor and cognitive dual task deficits, and may further impact the long-term health of astronauts. The objective of this study is to perform structural (volumetric MRI and diffusion tensor imaging (DTI)) and functional (sensorimotor and cognitive task) MRI (fMRI) and functional connectivity MRI (fcMRI)) brain imaging to identify changes in crewmember neurocognitive function due to long-duration space flight. The central hypothesis of this study is that measures of brain structure, function, and network integrity will change from pre to post flight in crewmembers.  Moreover, the prediction is that these changes will correlate with changes in the indices of cognitive, sensory, and motor function from pre flight, to in flight, and post flight, in a neuroanatomically selective fashion.

This study implements an interdisciplinary approach using cutting edge neuroimaging techniques and a broad range test battery of sensory, motor, and cognitive assessments to investigate neuroplastic and maladaptive brain changes in crewmembers following long-duration spaceflight.

This task also informs VIIP1 gap and the HCI and BMed Risks.
