BAERs from 16 subjects during 3 sessions varied in the latency or amplitude of some components depending upon level of arousal as indicated by EEG patterns. There was a general tendency for activation to produce the fastest responses with the largest amplitudes and for drowsiness to produce the slowest responses with the smallest amplitudes. The latency of P2 was significantly prolonged during drowsiness, relative to those during relaxation or activation. For right-ear stimulation, P5 latency was longest during drowsiness, and shortest during activation while for left-ear stimulation the shortest latency occurred during relaxation. The amplitudes of Wave II and Wave VII were significantly smaller during drowsiness than during activation. Although the differences were below the level of clinical significance, the data indicate a modification in the characteristics of brainstem transmission as a function of concurrent activity in other brain areas.

Prominent Peak

Averaged evoked responses (AER) to auditory stimuli presented to young children and adults were compared between awake and induced sleep conditions. Eight adults and twenty preschool children with normal hearing were tested before and during sedation at two suprathreshold levels with tone pips centered at 510, 1020, and 2040 Hz. Responses obtained during sedation assumed a distinctly different wave complex than those obtained under the awake condition. The P2 peak that is most prominent in the AERs obtained from awake subjects was diminished considerably under sedation and P3 became the prominent peak. Moreover, the P3 peaks in the AERs obtained under sedation were of considerably greater amplitude than the P2 peaks obtained in the awake condition. In all cases where responses were obtained from awake subjects, greater amplitude responses were obtained during sedation. The use of sedation with the preschool children proved to be most important in obtaining more detectable responses and permitting evoked potential audiometry with otherwise unmanageable children.
