Motor Sensory Performance (ED41)
Principal Investigator
Research Area:
Species Studied
Scientific Name: Homo sapiens Species: Human


The Mercury, Gemini, and Apollo programs proved that humans could function in a capable manner in space. Physiological changes, such as loss of bone calcium and muscle tissue, were established during these early manned space flight programs. However, little was known about human ability to perform intricate sensory-motor tasks during space flight. In general, fatigue affects the sensory and motor regions of the brain, decreasing sensory-motor skills. Many of the tasks that astronauts perform require that they maintain good sensory-motor skills for long hours. Therefore, the objectives of this experiment were (1) to measure changes in motor sensory performance resulting from prolonged space flight and (2) to compare Skylab performance data with existing ground-based data and data obtained during pre- and post- flight sessions.
