Effect of stimulus intensity variation on brainstem auditory evoked potentials. Maturational changes.
The effect of stimulus intensity variation on brainstem auditory evoked potentials in premature and full-term neonates has been studied in two experiments. They show that the effects are different according to age and to waves. The variation of latencies is greater the younger the child and it is clearer with wave I than waves III and V. The findings are discussed in terms of the maturation of the basal part of the cochlea.
