Description
OBJECTIVES:
Wayfinding is the cognitive phenomenon that allows humans to orient and navigate in spatial surroundings. Development of a sense of direction and location is dependent upon integration of visual, proprioceptive, and vestibular information. When this information is changed or lacking, wayfinding will be affected. Studies have shown that the microgravity environment of space significantly changes both proprioceptive and vestibular responses of astronauts causing motion sickness, perceptual illusions, and spatial disorientation until adaptation occurs. However, the behavioral and neurological effects following spaceflight are unknown.

In this investigation, the primary objective is to accomplish a comprehensive assessment of the cognitive and neurological changes that occur during long-duration spaceflight and during postflight re-adaptation to Earth’s atmosphere. The specific objectives of this investigation are to:

  1. Quantify the changes in spatial orientation skills that result from long-duration spaceflight
  2. Assess functional and structural neurological changes associated with altered spatial orientation skills resulting from long-duration spaceflight
  3. Evaluate if changes associated with long-duration spaceflight persist after long-term re-adaptation to terrestrial environments.
