The purpose of our research is to address the NASA requirement for ground-based and space flight studies examining the vestibular / autonomic interaction as related to adaptation to microgravity and readaptation to Earth. The primary goals of this work are to

- Understand the mechanisms by which behavioral (Autogenic Feedback Training Exercise AFTE - an autonomic conditioning procedure), and pharmacological countermeasures (e.g. scopolamine, promethazine and phenytoin) improve tolerance to motion and space motion sickness.

- Determine the treatment method most likely to be effective for facilitating adaptation to microgravity and re-adaptation to Earth with minimal side-effects.
