儿童弱视脑功率谱的研究山西医学院第一附属医院（０３０００］）谢斌，曲素芝，辛延峰脑血管研究所朵振顺，郝彩莲，郎小娥，程岗常州市广化医院陆淑玉，王淑玲为了探讨弱视与视皮层功能的关系，我们应用脑电功率谱（ＡＰ５），对弱视儿童的视皮层细胞功能活动情况进行了观察，并和正常儿童进行了对比，现将结果报告如下：资料和方法资料：弱视组２ｌ例，其中斜视性弱视９例，屈光不正性弱视８例，屈光参差性弱视４例。男１Ｏ例，女１１例；年龄最小为４岁，最大为９岁。对照组２０例，年龄最小为６岁，最大为１１岁，男女各１０例，双眼视力良好。两组经严格体检，除弱视外，排除了脑、眼以及全身其他系统疾病，全部受检对象在检查前均未服用过任何影响脑功能的药物。方法：采用日本光电公司的５１１４型脑电图仪和国产ＮＤ－１型脑电地形图仪描记，按国际１０～２０系统放置安放电极，１４导程同时记录，双耳为参考电极，在安静闭目状态下，进行单、双导联描记，时间常数为０．３Ｓ，高频滤波３５Ｈｚ，将不含明显伪差的脑电信号输入信号处理机内，间隔５μＳ，采样点１０２４个，对背景脑电曲线进行模数转换，快速付立叶分析，把记录下的脑电波频率分为６（２～３．８），θ（４～７．８），α（８ Children’s visual acuity spectrum of weakness First Affiliated Hospital of Shanxi Medical University (03000]) Xie Bin, Qu Suzhi, Xin Yanfeng Institute of Cerebrovascular Research Duzhenshun, Hao Cailian, Lang Xiaoe, Cheng Gang Changzhou Guanghua Hospital Lu Shuyu, Wang Shuling To explore Amblyopia and visual cortex function, we use the EEG power spectrum (AP5), visual function of amblyopic children in the visual cortex was observed and compared with normal children, the results are reported as follows: Materials and Methods: Amblyopic group 2l cases, including strabismic amblyopia in 9 cases, 8 cases of refractive amblyopia, anisometropic amblyopia in 4 cases. Male 1O cases, 11 females; the youngest is 4 years old, the maximum is 9 years old. Control group of 20 patients, the youngest was 6 years old, the maximum was 11 years old, 10 men and women in each case, binocular vision was good. After strict physical examination, except for amblyopia, the two groups excluded other diseases of the brain, eyes and other systemic diseases. All subjects had not taken any drugs that affect brain function before the examination. Methods: The 5114 electroencephalograph of Japan Optoelectronic Co., Ltd. and domestic ND-1 electroencephalograph were used to record the electrodes. The electrodes were placed in the international system of 10 to 20, while the 14 leads recorded at the same time. The ears were used as reference electrodes, Close state, the single and double lead tracing, the time constant of 0.3S, high-frequency filtering 35Hz, will not contain significant artifacts EEG signals into the signal processor, interval 5μS, sampling points 1024 pairs of The background EEG curve was converted to analog form and quickly analyzed by Fourier transform. The recorded brain wave frequencies were divided into 6 (2 ~ 3.8), θ (4 ~ 7.8), α (8
