Answer

Answer

Schwarz et al showed prolonged interpeak latencies (I-III, I-V, III-V, IV-V) and delayed absolute latencies of waves II, III, V, and I, at least on 1 side, in the BAEP. [35] The auditory pathways are near the respiratory control centers in the brainstem; therefore, the electrophysiologic abnormalities of wave III and the IV-V complex may be a reflection of the disturbed central control of ventilation.
