We conducted an event-related potential (ERP) study using a 256-channel dense sensor array electroencephalography (EEG) system to examine how, and if the P200 neurophysiological signal is sexually dimorphic. We had two groups of participants: females (n= 15, mean age = 40.6 years old) and males (n = 15, mean age = 39.0 years old). ERPs from all participants were recorded while the participants performed an oddball task. Results showed that males on average had a significantly larger P200 peak amplitude and a significantly shorter P200 latency period. These results indicate that the P200 ERP is affected by sex. Therefore, suggesting that sex differences exist on an electrophysiological level, which may aid in better understanding of sex-biased biological influences, behaviors, neuropsychiatric disorders, and general brain function.
我们使用256通道密集传感器阵列脑电图（EEG）系统进行了一项事件相关电位（ERP）研究，以检验P200神经生理信号是否存在性别差异以及如何存在性别差异。我们有两组参与者：女性（n = 15，平均年龄 = 40.6岁）和男性（n = 15，平均年龄 = 39.0岁）。在参与者执行Oddball任务时记录所有参与者的ERP。结果显示，男性的P200峰值平均幅度明显更大，P200潜伏期明显更短。这些结果表明，P200 ERP受性别影响。因此，表明在电生理水平上存在性别差异，这可能有助于更好地理解性别偏见的生物学影响、行为、神经精神疾病和一般脑功能。
