本研究考察了电极放置对正常听力受试者早期听觉诱发反应的影响。电极分为非反相电极、反相电极和普通电极。评估了10种常用的电极组合。测量每个电极组合的波I、波III和波V的振幅和潜伏期。10种电极组合中的任何一种都没有观察到波I， III或V的潜伏期平均差异。同样，在10个电极蒙太奇中没有发现具有统计学意义的波I或波III振幅差异。然而，在顶点放置非反相电极（0.5 .mu）时，发现波V振幅较大。V)与上前额（0.39 μ V）相比。此外，在第七颈椎/前额、颈/前额和颈/颈部放置反置/共电极时，波V振幅更大。0.50 .mu。V)比乳突/乳突和乳突/前额位置(约。0.40 .mu.v)。因此，三种电极组合产生了最大的波V振幅。非反相电极、反相电极和普通电极的放置位置分别为(a)顶点-第七前额，(b)顶点-颈部-前额，(c)顶点-颈部-颈部。
This study examined the effects of electrode placement on the early auditory evoked response in normally hearing subjects. The electrodes are termed noninverting, inverting, and common. Ten commonly used electrode combinations were evaluated. Both amplitudes and latencies of Waves I, III, and V were measured for each electrode combination. No mean differneces in latencies were observed for Waves I, III, or V with any of the 10 electrode combinations. Similarly, no statistically significant Wave I or Wave III amplitude differences were found among the 10 electrode montages. However, larger Wave V amplitudes were found with placement of the noninverting electrode at the vertex (0.5 .mu.v) as compared to the upper forehead (0.39 .mu.v). Moreover, Wave V amplitudes were larger for inverting/common electrode placements at the seventh cervical vertebra/forehead, neck/forehead, and neck/neck (.apprx. 0.50 .mu.v) than for mastoid/mastoid and mastoid/forehead placements (.apprx. 0.40 .mu.v). Thus, three combinations of electrodes gave the largest Wave V amplitudes. These placements for the noninverting, inverting, and common electrodes, respectively, were (a) vertex-seventh-forehead, (b) vertex-neck-forehead, and (c) vertex-neck-neck.
