A significant increase in calculation ability was observed in the glucose, fructose and sucrose administration groups during both the first and second half of the Uchida Kraepelin test. There was no significant difference in alpha waves between carbohydrate groups (glucose, fructose and sucrose) and control groups at baseline. After a stress situation, there was a significant increase in alpha waves at 11-20min (p<0.05) in glucose, 11-20min (p<0.01) and 21-30min (p<0.01) in fructose, and 0-10min (p<0.05) in sucrose compared, with each control group. There was no significant difference in beta waves in any of the paired groups.
