Possible connection between the nasal cycle and consciousness

It is shown that there is a connection between the dynamics of the nasal cycle and the consciousness states of the brain. Accordingly to hypothesis, the switch of dominated airflow between left and right nostrils in time becomes only in consciousness states of the brain (in awake state, in REM dream and in dream of stages 1-2 of the non-REM sleep). This finding gives possibility to use nasal cycle as ‘marker’ for consciousness
