Event-related potentials (ERPs) were elicited with an auditory discrimination paradigm in 20 adult female subjects on the first day of their menstrual cycles and approximately 14 days later. The amplitude and latency of the N1, P2, N2 and P3 (P300) components were measured for the two assessment times. No differences in either amplitude or latency for any of the components were observed as a function of menstrual cycle. Half the subjects who took oral contraceptives were compared to the other half who did not. No differences or interactions between these subgroups were obtained for any component amplitude or latency. It was concluded that menstrual cycle and use of oral contraceptives do not affect the P3 or other ERP components.
在20名成年女性受试者月经周期的第一天及其后约14天，采用听觉辨别范式诱发事件相关电位（ERP）。在两个评估时间测量N1、P2、N2和P3（P300）成分的波幅和潜伏期。未观察到任何成分的波幅或潜伏期随月经周期而有差异。将服用口服避孕药的一半受试者与未服用的另一半受试者进行比较。在这些亚组之间，任何成分的波幅或潜伏期均未发现差异或相互作用。得出的结论是，月经周期和口服避孕药的使用不会影响P3或其他ERP成分。
