1. Do The Aerospace Spin Sponsored by a grant from the NASA Space Biomedical Research Institute

2. How many senses do you have? Are there more?

3. I see dead people.

4. Humans have at least 8 physical senses. Sense of motion Sense of Position Sense of hunger/thirst

5. The primary purpose for our senses is biological survival The senses work in concert to : find things we need to live give us a 3-dimensional view of our world and our position within it make us aware of relative motion identify potential hazards

6. Can The Senses Be Fooled?

7. Are the gray lines warped or parallel?

8. Are the gray lines warped or parallel?

9. Graveyard Spiral

10. How do humans detect changes in motion? (acceleration and deceleration)

11. Objects at rest remain at rest and objects in motion remain in motion unless acted upon by an unbalanced force. Newton’s First Law of Motion LAW OF INERTIA

12. Human Vestibular System

13. Robert Bárány 1914 Nobel Laureat in Medicine for his work on the physiology and pathology of the vestibular apparatus. 1876-1936 Austrian-Hungarian/Swedish physician and otoneurologist

14. Structure of the Ear

16. SENSING ANGULAR MOTION FIRST CASE

17. CLOCKWISE ACCELERATION AROUND YAW AXIS ENDOLYMPTH FLUID LAGS COUNTERCLOCKWISE (INERTIA!) CUPULA DEFLECTSNERVES SEND SIGNAL TO BRAINBRAIN INTERPRETS - CLOCKWISE ACCELERATION AROUND THE YAW AXIS CORRECT!

18. SENSING ANGULAR MOTION SECOND CASE

19. CLOCKWISE MOTION CONTINUES - ACCELERATION STOPS INTERNAL FRICTION CAUSES ENDOLYMPTH FLUID TO MOVE AT SAME RATE AS CANAL CUPULA RETURNS TO RELAXED CONDITIONNERVES SEND SIGNAL TO BRAINBRAIN INTERPRETS - YAW AXIS ANGULAR ACCELERATION HAS STOPPED. FALSE!

20. SENSING ANGULAR MOTION THIRD CASE

21. CLOCKWISE YAW MOTION STOPS ENDOLYMPTH FLUID CONTINUES TO MOVE CLOCKWISE (INERTIA!) CUPULA DEFLECTS NERVES SEND SIGNAL TO BRAIN BRAIN INTERPRETS - COUNTERCLOCKWISE ANGULAR ACCELERATION AROUND THE YAW AXIS FALSE!

22. LACK OF GRAVITY’S EFFECTS CAN CAUSE DISORIENTATION MORE THAN HALF OF ALL ASTRONAUTS EXPERIENCE SPACE ADAPTATION SYNDROME UPON ARRIVAL IN SPACE MORE THAN HALF OF ALL ASTRONAUTS EXPERIENCE SPACE ADAPTATION SYNDROME UPON ARRIVAL IN SPACE WHICH WAY IS UP?
