摘要

脑电图(EEG)是一种功能强大、价格低廉且未充分利用的神经生理学诊断工具。由于脑电图信号包含了丰富的脑功能信息，因此利用频谱技术分析脑电图信号的方法很多。本文对8例6 ~ 11岁亚斯伯格症患者和10例年龄匹配的对照组进行了短时傅立叶变换(STFT)脑电图的19个通道。用方差分析评估这些值。结果表明，两组之间的γ波段(34-44Hz)有94.4%的差别。112对19通道脑电图的相干性测量显示，右颞叶与额叶之间的连通性以及右颞叶与其他叶之间的连通性存在异常。

Abnormalities in Connectivity of Quantitative Electroencephalogram Background Activity in Asperger Disorders with Short Time Fourier Transform and Coherence Values

Electroencephalography (EEG) is a powerful, inexpensive, and underutilized neurophysiology diagnostic tool. Since EEG signals contain a wealth of information about brain functions, there are many approaches in analyzing EEG signals with spectral techniques. We have used short time Fourier transform ‎‎(STFT) at 19 channel’s of EEG for 8 Asperger ‎disorders (6-11 years old) and 10 age matched control ‎subjects. The values were assessed with variance analysis. Results are shown that gamma band (34-44Hz) has 94.4% discriminate between two groups. Coherence measures at between 112 pairs of 19 channels EEG are shown there are abnormalities at ‎connectivity between in right temporal lobe and frontal lobe and connectivity between right temporal lobe with other lobes.
