Theory 76/Hiccups/Rate lens
Hiccup Rate Is Reflex Cycling
The claim
Hiccup frequency is set by the rate of the vagal reflex cycle rather than by diaphragm irritability.
01Mechanism
Each hiccup is one iteration of a reflex loop; the loop time sets the rate.
02Prediction
Frequency should track reflex cycle time.
03Refutation
Frequency tracking irritation would remove the loop.
