EXPERIMENT INFORMATION

Space Adaptation Syndrome Experiments (SASE)
Principal Investigator
Research Area:
Neurophysiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Many astronauts experience space adaptation syndrome, which may include illusions, loss of knowledge of limb position, nausea and vomiting. These symptoms may occur because of conflicting messages about body position and movement which the brain receives from the eyes, the balance organs of the inner ear and gravity sensing receptors in the muscles, tendons, and joints.
