Key findings

  • Glucose produced larger EEG effects than sucrose, fructose or corn starch
  • Absolute blood glucose level was the main predictor of EEG change
  • Changes were concentrated in left parietal-occipital and left temporal regions
  • Authors note implications for how cognitive function is studied and assessed

This study looked at whether different kinds of carbohydrate affect the brain differently. Four carbohydrates (glucose, sucrose, fructose and corn starch) were given by mouth as tolerance tests across 17 test trials, while EEG and blood sugar were tracked together for five hours. Glucose produced the largest EEG changes, and the absolute blood glucose level was the main driver of the changes, which appeared mostly over left parietal-occipital and left temporal areas.
