研究了碳水化合物物质复杂性的变化对大脑功能的不同影响。在 17 项试验中，葡萄糖、蔗糖、果糖和玉米淀粉分别作为口服碳水化合物耐受性测试的一部分进行施用。在 5 小时内同时监测脑脑电图变化和血糖水平。葡萄糖溶液比其他三种碳水化合物溶液产生更显着的脑电图效应。绝对血糖水平是主要在左顶枕叶和左颞叶皮质区域发现的皮层电变化的主要决定因素。讨论了认知功能研究和评估的意义。
Variations in the complexity of carbohydrate substances were studied with respect to their differential effects on brain function. Glucose, sucrose, fructose and corn starch were each administered as part of an oral carbohydrate tolerance test during 17 test trials. Brain EEG changes and blood glucose levels were monitored concurrently throughout a 5 hour period. The glucose solution produced more substantial EEG effects than the other three carbohydrate solutions. Absolute blood glucose level was the primary determinant of electrocortical changes found predominantly in the left parietal-occipital and left temporal cortical regions. Implications for the study and evaluation of cognitive function were discussed.
