A number of concepts and facts from the vision domain are of interest and value to otologists. Not only the similarities but also the differences between the two sensory systems are enlightening. The paper discusses the similar ranges of sensitivity to quanta of energy and the biological mechanisms whereby the physical stimuli are transformed logarithmically, coding of the physical stimulus by single cells in the optic and the auditory nerves, principles of neural integration in the brainstem and midbrain nuclei, the point-to-point relationship between cortical activity and certain aspects of the physical stimulus, the eye and ear as channels of information, and cross- modality facilitation and inhibition.
