ABOUT THIS EPISODE
Did you know that your sense of smell can affect your brain function? In this episode, I sit down with Dr. Michael Leon, a professor emeritus of neurobiology and behavior at UC Irvine, to discuss a fascinating, yet simple intervention that can improve memory and brain function: olfactory enrichment. We explore how odors, when introduced during sleep, can trigger dramatic improvements in verbal memory and even stimulate changes in the brain's memory circuits.
Dr. Leon dives into his research on the relationship between the sense of smell and the brain's memory pathways. He explains how olfactory loss is linked to various neurodegenerative conditions, such as Alzheimer's, and how reintroducing odors during sleep can have a profound impact on cognitive function. We also discuss the development of a device, the Memory Air, which makes olfactory enrichment easily accessible at home.
This conversation sheds light on how olfactory stimulation can provide a simple, non-invasive, and safe solution to brain health and memory loss.
“The sense of smell is the only sense that has a superhighway access to the memory centers and the emotional centers of your brain.”
~ Dr. Michael Leon
