Olfactory Pathways as Entry Point to the Nervous System
Recent studies indicate the nose and the olfactory system are direct pathways to the
brain. The blood / brain barrier that helps protect the brain from substances in the blood
stream does not necessarily protect the brain from substances that are inhaled.
