What’s the secret to keeping your balance? The ear does more than hear: it helps us stay stable by perceiving movements and gravity. Elegant sensors deep within the skull detect every twist, turn, and tumble, powering swift reflexes that keep vision and balance steady. This is the vestibular system. It’s primordial and ubiquitous: every animal has one, and even plants have a rudimentary version. It works so well that we take it for granted—until it fails. How does this remarkable system function? What happens when it goes haywire? How can modern medicine treat vestibular disease?
The Great Balancing Act tells the story of the vestibular system, from T. rex hearing organs to cochlear implants, and from the unsung power of hair cells to inner-ear problems in outer space. Combining neuroscience, history, and medicine, Jeffrey D. Sharon—a vestibular doctor and researcher—explains the sense of balance using accessible language and wry humor. He recounts how pioneering scientists solved the mysteries of the vestibular system and shows why it is necessary for spatial reasoning and abstract thought. Sharon explores the devastating consequences of vestibular problems such as vertigo, dizziness, and imbalance, offering an expert, patient-friendly look at emerging and future treatments. Engaging and entertaining, this book invites readers to discover a little-known yet vital part of ourselves.
"How does the vestibular system integrate a barrage of sensory information to enable animals to navigate the world? In ‘The Great Balancing Act,’ Jeffrey Sharon addresses these and other questions about this elegant sensory system that helps regulate proprioception and spatial reasoning. Sharon discusses how the vestibular system evolved and how it interacts with brain areas that process vision, abstract thought and memory. He ends the book on a forward-looking note, explaining how insights from basic neuroscience are propelling exciting advances in prosthetic implants and gene therapies to help rebuild cellular structures in diseased vestibular systems." - The Transmitter
