Nasal Cycle Dilemma: Nasal Cycle Is Associated to Brain Wake/REM States or Is Associated to Conscious State in Them?

Abstract

Experimental and theoretical arguments have been described in favor of the hypothesis that the nasal cycle reversals of the nostril’s airflow occurs only in the consciousness states of the brain (during awake/wake state, REM state and during dreams in St.1, 2 of the non-REM sleep). This finding gives possibility to use nasal cycle as “marker for consciousness states”. An idea for clinical application of the hypothesis is proposed.
