title: Lateralization and discrimination of dichotic clicks: evidence from patients with brainstem lesions and normal cohorts.
abstract: The ability to lateralize and discriminate dichotic clicks was tested in multiple sclerosis patients with normal audiograms and in normal cohorts. Lateral position spread over a greater range with interaural level differences than with interaural time differences, and was related to the two asymmetries by different functions. Measures of binaural acuity were inversely related to the slopes of the two functions. One group of patients performed normally with both types of interaural asymmetry, another group performed normally only with level differences; a third group of patients could not perform normally with either.
