分析105例大脑半球肿瘤的脑电图资料,发现脑前部肿瘤近半数有局部β波抑制,脑后部肿瘤均抑制α波;额颞部均有异常脑电灶者,额叶肿瘤显著多于颞叶肿瘤;中央区肿瘤较多出现局灶性θ波,具此征者以良性和边界清楚的肿瘤居多;横联双导有助于矢旁区肿瘤的定位;额颞区肿瘤同侧外侧裂周围出现阵发性θ或复形δ波有定位意义;全脑阵发性节律波,在病变区其波幅/频率/波形/持续时间多于它处有别,此点亦有助于定位。 Analysis of 105 cases of brain hemisphere EEG data found that nearly half of the anterior pituitary tumor inhibition of local β-wave, posterior cerebral tumors were inhibited α-wave; frontotemporal abnormal EEG are, the frontal lobe tumor was significantly more In the temporal lobe tumor; central tumor more focal tau wave, with the majority of benign and clear border cancer; horizontal double guide contribute to the location of the tumor adjacent to the side; frontotemporal tumor ipsilateral Occurrence of parietal lateral cleft θ or complex shape δ wave positioning significance; whole brain paroxysmal rhythm wave in the lesion area of ​​its amplitude / frequency / waveform / duration more than it at this point also helps Positioning.
