Sensorimotor Adaptation

Team Overview
Astronauts on exploration space missions will experience gravitational transitions, as well as extended periods of micro- and fractional gravity, with associated adaptation in their sensory and motor systems. Disorientation, vestibular-autonomic responses, and changes in vision, proprioception, cognition, balance and motor control may lead to impaired performance and compromised mission success.

In addition to identifying individual risk factors, the Sensorimotor Adaptation Team examines sensory systems, their interactions, and integration with the brain and motor behavior relevant for long-duration space missions. Research to understand fundamental physiological and biomolecular processes is complemented by development of personalized countermeasures, with particular emphasis on high priority gaps and operational needs.

The Team's research will have terrestrial benefits for those suffering from an array of neurosensory and motor conditions, especially in the elderly where falls are endemic.
