Why we get dizzy | Kristen Steenerson

From Our Neurons to Yours

Welcome back to "From Our Neurons to Yours," a podcast where we criss-cross scientific disciplines to take you to the frontiers of brain science. This week, we explore the science of dizziness with Stanford Medicine neurologist Kristen Steenerson, MD, who treats patients experiencing vertigo and balance disorders.

In our conversation, we'll see that dizziness is not a singular experience but rather a broad term encompassing a variety of different sensations of disorientation. We learn about the vestibular system, a set of biological "accelerometers" located deep within the inner ear that detect linear and angular acceleration, helping us perceive motion, orientation, and our connection to the world around us.
We also discuss a wearable medical device Dr. Steenerson and colleagues at the Wu Tsai Neurosciences Institute are developing a wearable device to measure the activity of the vestibular system by tracking a patient's eye movements. With the ability to study this mysterious system in unprecedented detail, we're on the verge of learning more than ever about this misunderstood "sixth sense."
