The authors studied the relationship between brain metabolic activity and quantitative electroencephalographic power in AIDS. Basal ganglia and thalamic metabolic activity, measured with positron emission tomography, correlated positively with EEG power in the 6-10-Hz band across most head regions. Metabolic activity of anatomically defined cortical regions did not correlate with EEG power recorded over each region. These results support previously reported associations between abnormalities in subcortical metabolic activity and EEG activity. The lack of correlation between cortical metabolic activity and EEG activity suggests that previously observed abnormalities in EEG activity are primarily subcortical in origin.
作者研究了艾滋病患者脑代谢活动与定量脑电图功率之间的关系。通过正电子发射断层扫描测量的基底神经节和丘脑代谢活动，在大多数头部区域与6-10赫兹频段的脑电图功率呈正相关。解剖学定义的皮质区域的代谢活动与每个区域记录的脑电图功率不相关。这些结果支持了先前报道的皮质下代谢活动异常与脑电图活动之间的关联。皮质代谢活动与脑电图活动之间缺乏相关性表明，先前观察到的脑电图活动异常主要起源于皮质下。
