| 中文摘要 | 双眼竞争是两侧不相融合的单眼图像刺激形成主观意识交替占优的现象。为实现对双眼竞争中意识交替平均速率的客观检测,提出了一种将相位锁定与互功率谱估计相结合的脑电分析算法,利用频率标记双眼竞争过程中记录的脑电信号。在对6例实验数据的分析中,客观检测平均速率与主观报告相差10%以内。该方法抗噪性能好,不需要主观参与,适用于无法言语表达的婴儿及老人受试。平均交替速率作为一项辅助诊断指标,对老年痴呆症、儿童多动症等多种神经障碍疾病的诊断具有应用前景。; When the human visual system cannot reconcile dissimilar images seen by each eye,the perception alternates between the two images,a process known as binocular rivalry.This paper presents an objective method to capture average the perceptual alternating rate based on a combination of the phase locking value and a cross power spectral density analysis of electroencephalograms during binocular rivalry.For the six subjects who participated in the experiment,the relative error between the measured and subjective rate was within 10%.This method is robust with no subjective information needed;therefore,it is especially useful with non-verbal infants.Moreover,the average alternating rate is a reasonable parameter for diagnosing several neuropathies such as dementia and minimal brain dysfunction. |
