Food is understood to motivate behavior.
But it’s not just hunger that does it — not just the need for physical sustenance. People who get their nutritional needs met with a bland, uninspiring diet will still have their thoughts consumed by fantasies of flavor – dreamt-of meals of smorgasbords of exotic cuisine. Few “lost in the wilderness” stories or prison sagas don’t feature food becoming a borderline obsession, even among well-fed people.
Neurogastronomy is the study of flavor perception — a new, interdisciplinary field at the conjunction of psychology, neuroscience and food science. Its proponents’ interests go broader still, into areas of environmental sustainability and population-level health systems.
Dr. Tim McClintock, Ph.D. and Dan (Dong) Han, Psy.D. are colleagues at the University of Kentucky College of Medicine, where McClintock is a Professor of Physiology and Han an Associate Professor of Neurology, Neurosurgery, and Physical Medicine & Rehabilitation. They are each at the forefront of the ripening movement to apply (and extend) our understanding of how smell, taste, and texture combine to create flavor.
The possibilities presented by being able to adjust the dials on one of our most universal drives can’t be overstated. Flavor is a motivator for everyone — and almost all the time. Sleep motivates, but only when we’re tired. Sex motivates, but more in some times of life than others. But chocolate always tastes good.
“What if we could make kale or brussels sprouts induce the same pleasure as chocolate?”

Thinking Differently About Flavor.
Taria Camerino is a gustatory synesthete — meaning that her perceptual senses are unusually wired compared to your standard-issue human brain. She says that while she can’t remember visual images, flavor is the sense by which she interfaces with the world. Luckily (perhaps inevitably), she is a highly sought-after chef. Her work has included interpreting music into flavor — sort of a sensory translation exhibit.
In Episode #202, she explains her technique for designing recipes that include the least traditional of ingredients. (Example: Granite.) And along the way, we discuss the multi-dimensional topic of flavor with experts working across the neurogastronomic spectrum:
- Can the bad taste good?
- Can the good taste better?
- Are humans really the olfactory underdogs we’re widely believed to be?
- Can the tasteless feel their flavor restored?
