The central rhythm of the nasal cycle.
The resistance to air flow of each nasal passage was recorded in 2 subjects over a period of 7 days. The cyclical changes in nasal resistance observed were very regular, with a consistent pattern apparent over the period of study. The regular changes in nasal resistance recorded under laboratory conditions may be directly related to changes in activity of an autonomic centre in the brain.
