摘要
目的探讨脑损害患者数字工作记忆脑区的激活特点。方法采用1.5 T磁共振扫描仪对9例脑损害患者在进行数字工作记忆时进行扫描,结果与正常对照者进行比较。结果与正常对照组相比,脑损害组大脑皮质对数字工作记忆的激活区域和强度有不同程度的减少,激活广泛而散在,左右半球脑区激活的差距减小。同时,不同脑损害患者也有各自激活特点。结论脑损害患者在数字工作记忆时可在损害区域附近或对侧半球对应区域甚至其他区域出现激活。
Objective To study the characteristics of brain activity of digital working memory in patients with brain injury.Methods Nine patients with brain injury were scanned by 1.5 T MRI during the digital working memory.The results were compared with normal controls.Results Compared with normal control group,the range and intensity of activity of brain cortex during the digital working memory in brain injuried group were decreased.The activity range of brain was wide-ranging and scattered,and the difference between left hemisphere and right hemisphere was reduced.The characteristics of brain activity in patients with different brain injury were different.Conclusion Brain activity regions can be near by the injured regions or on contralateral regions and other regions during the digital working memory in patients with brain injury.
