The Gravity Sensors
When a kidney is removed, dizziness, unsteadiness, and loss of plantar sensation occur.
At this time, the sense of balance is normal, and there are no abnormalities in the eyes and ears,
indicating that the kidney itself is related to the sense of balance.
Plantar sensation is related to the perception of gravity.
From research on astronauts in spacecraft, it is known that symptoms such as
decreased blood flow, muscle atrophy, skeletal distortion, and autonomic nervous system disorders occur under zero gravity.
Therefore, in seitai that focuses on gravity,
the function of blood flow and the autonomic nervous system is improved by rebooting the gravity sensors on the body surface.
