记录了14名年轻人和14名老年人的嗅觉事件相关电位(OERP)，并操纵乙酸异戊酯的气味强度来评估嗅觉刺激强度。年轻受试者产生的N1/P2、N2/P3波幅显著高于年长受试者，而N1、P2和N2潜伏期显著低于年长受试者。与两个年龄组的最低气味浓度相比，中等和高度气味浓度引起的P2和N2潜伏期显著缩短。气味浓度似乎会影响嗅觉刺激信息处理的速度，而与年龄无关。(C)1999 Elsevier Science B.V.保留所有权利。
Olfactory event-related potentials (OERPs) were recorded in 14 young and 14 older adults, with odor strength of isoamyl acetate manipulated to assess olfactory stimulus intensity. Young participants produced significantly larger N1/P2, N2/P3 amplitudes and shorter N1, P2 and N2 latencies than older participants. Medium- and high-odor concentrations elicited significantly shorter P2 and N2 latencies than the lowest concentration for both age groups. Odor concentration appears to affect the speed of olfactory stimulus information processing regardless of age. (C) 1999 Elsevier Science B.V. All rights reserved.
