This study evaluated the characteristics of the middle latency response MLR and the related steady state evoked potential SSEP in a total of 36 neonates. The reports of previous investigators have cast doubt on the existence of both the MLR and SSEP in neonates. The measurements in these studies were obtained, however, using stimulation and recording parameters that are appropriate for adults. Since virtually all other aspects of neonate audition differ significantly from comparable adult attributes, one goal of this study was to determine the appropriate parameters with which to obtain a valid MLR and SSEP in very young children. Other goals of this study included 1 evaluation of two different algorithms for low-frequency sensitivity prediction using the SSEP 2 investigation of the stability of the SSEP over repeated trials and 3 elucidation of the relationship the neonatal MLR to later occurring auditory evoked potentials.
