A METHOD OF MEASURING THE ACTIVITY OF A BIOLOGICAL SYSTEM

摘要

The method and apparatus for measuring the activity of a biological system, particularly the vestibular organ, to a single stimulus by applying the stimulus to the biological system, detecting an electrical response of the system to the single stimulus and processing the electrical response to identify at least one repeated periodic signal. An alternative method and apparatus for measuring the activity of a biological system is described where, in the absence of any external stimulus to the biological system, the method includes detecting an electrical output produced by the system and processing the electrical output to identify a repeated periodic signal. Tinnitus may be detected by this method using an electrode in the tympanic recess.
