Summary Table of Contents Author Biography

The Vestibular System: A Sixth Sense is an integrative look at the vestibular system and the neurobiology of balance. Written by eight leading experts and headed by Jay M. Goldberg, this book builds upon the classic by Victor Wilson and Geoffrey Melville Jones published over 25 years ago and takes a fresh new look at the vestibular system and the revolutionary advances that have been made in the field. A core reference work for sensory neurobiologists, and also neurologists and other clinicians interested in postural control, motion sickness an... MORE
