The science of Olfactory Enrichment is a fundamental breakthrough discovered by Dr. Michael Leon, Professor Emeritus, Neurobiology and Behavior, University of California Irvine, along with a group of eminent scientists around the world. Named one of the top 1% of scientists in the world, Dr. Leon discovered that when the olfactory system is stimulated in a very specific way, your brain function, sleep and memory are improved. To get these brain benefits, a variety of scents must be delivered consistently every day. So Dr. Leon developed Memory Air™, a device that does the whole process for you automatically, while you sleep!
