目的探讨临床上重度腕管综合征时,正中神经体感诱发电位中潜伏期波N60在诊断中的价值。
Objective To evaluate the use of median nerve somatosensory evoked potentials(SEP)wave N60 in the diagnosis of severe carpal tunnel syndrome(CTS).
结果:大剂量免疫球蛋白可抑制部分致痫大鼠皮层诱发电位的振幅、脑电图痫样波的频率和振幅,使诱发痫样波发生的潜伏期延长。
RESULTS: the amplitude of the evoked potential and the frequency and amplitude of the epileptiform discharges in cerebral cortex were partially restrained.
由于小波变换在时域和频域上都具有良好的局部化特性,基于小波变换的去噪方法,可以达到从单次样本中提取视觉诱发电位的目的。
Due to the good localization feature of the wavelet transform both in time plane and in frequency plane, a wavelet-based de-noise method is presented for extracting EPs in single trails.
