Using the Xe133 inhalation technique, measurements of the blood flow to the left and right parietal and temporal regions of the cerebrum were obtained in 5 healthy individuals while simultaneously recording their EEGs. Up to 3 measurements were obtained from each of the subjects the first while they were mentally at rest and the others while they were engaged in prescribed forms of mental activity. Relationships between the measured blood flow through grey matter, initial slope index, relative grey weight, percent grey flow and power in the delta, delta-theta, alpha, beta and gamma rhythms of the EEG were examined. The results showed that for the subject group as a whole there was a strong correlation between the power present in the low frequency components of EEG and the grey flow and relative grey weight parameters of blood flow. On an individual basis, the observed relationships were highly variable particularly at high flow rates and at low relative grey weights, but became much more definitive at low flows and high weights. The results as they relate to previous work of this kind are discussed.
采用Xe133吸入技术,对5名健康个体大脑左右顶叶和颞叶区域的血流进行了测量,同时记录他们的脑电图。每个受试者最多获得3次测量值,第一次是在他们精神放松时,另外两次是在他们进行规定形式的精神活动时。研究了通过灰质的测量血流量、初始斜率指数、相对灰质重量、灰质血流百分比与脑电图δ、δ-θ、α、β和γ节律功率之间的关系。结果表明,对于整个受试者组,脑电图低频成分中的功率与灰质血流和血流相对灰质重量参数之间存在很强的相关性。就个体而言,观察到的关系变化很大,特别是在高流速和低相对灰质重量时,但在低流速和高重量时变得更加明确。讨论了这些结果与此前此类研究工作的关系。
