Abstract
This investigation examines the relationship between the head size of 22 normally hearing individuals and the latency of their respective auditory brainstem responses (ABR). The absolute latency of wave V and the I-V interpeak interval were examined in 12 female and 10 male subjects with varying head sizes. Strong positive correlations were obtained between head size and the latency of both wave V and the I-V interpeak interval. The evidence suggests that this relationship is based upon subject differences in brain size which is reflected in head size. Head size appears to be an important source of intersubject variability which should be considered in order to increase the clinical usefulness of the ABR. Cette recherche étudie le rapport qui existe entre le volume de la těte et la latence des réponses auditives du tronc cérébral (ABR) chez 22 individus possédant une ouie normale. Nous avons étudié la latence absolue de l'onde V et Pintervalle entre pics des ondes I-V chez 12 femmes et 10 hommes dont le volume de la těte variait. Nous avons observé des corrélations positives fort con-vaincantes entre le volume de la těte et la latence de l'onde V et de l'intervalle entre pics 1-V. Cette preuve bien établie suggère que ce rapport est lié à la différence entre le volume du cerveau qui correspond au volume de la těte. Le volume de la těte semble ětre une source importante de variabilité interindividuelle et devrait ětre pris en considération afin d'augmenter l'application clinique de l'ABR.Keywords
