(Weizmann Institute of Science) If an unconscious person responds to smell through a slight change in their nasal airflow pattern - they are likely to regain consciousness, according to a new study by Weizmann Institute scientists published Wednesday in the journal Nature. 100% of the unconscious brain-injured patients who responded to a "sniff test" developed by the researchers regained consciousness during the four-year study period.
