We evaluated 24 testable children with unilateral epileptic foci, with and without radiologically demonstrable lesions, to determine if the normal pattern of cerebral dominance is changed by the presence of an epileptic focus. Verbal and figural stimuli were presented tachistoscopically to the right and left visual hemifields to investigate the specific abilities of the two hemispheres. Three blocks of stimuli consisting of two-letter patterns, three-letter patterns, and meaningful two-syllable words were used as verbal stimuli to assess the abilities of the left hemisphere. A test consisting of localizing a dot on a 3 x 3 matrix was used to assess the abilities of the right hemisphere. Six normal children were chosen as controls. In all groups, specialization of the epileptic hemisphere was lost. The presence or absence of a radiologically demonstrable lesion did not influence this pattern.
我们评估了24名患有单侧癫痫病灶的可测试儿童，这些儿童有的有影像学可显示的病变，有的没有，以确定癫痫病灶的存在是否会改变大脑优势的正常模式。通过速示器向右侧和左侧视觉半视野呈现语言和图形刺激，以研究两个半球的特定能力。由两个字母的图案、三个字母的图案和有意义的双音节单词组成的三组刺激被用作语言刺激，以评估左半球的能力。一项在3×3矩阵上定位一个点的测试被用于评估右半球的能力。选择了6名正常儿童作为对照。在所有组中，癫痫半球的特化都消失了。影像学上可显示的病变的有无并不影响这种模式。
