For many years, physicians have had to be content with rather rudimentary techniques for assessing the function of the vestibular apparatus. In the past few decades a number of new methods have been devised for studying this part of the nervous system. These advances in technology and laboratory diagnosis were the subject of a symposium in September 1980, and are published now as part of the ongoing UCLA Forum in Medical Sciences.
As one might expect from a collection of 23 individual presentations, the quality of the contributions is uneven. A lack of uniformity derives also from the complexity and nascent state of much of the subject matter and the fact that the 30 contributors comprise neurologists, ophthalmologists, and otolaryngologists, among others, each with a somewhat different point of view. Nevertheless, the volume does contain a number of substantive articles on the physiological basis of vestibular disturbances and on modern
