Coffee and a Sweet Treat to Think Better? Caffeine and Glucose Combined Improves the Efficiency of Brain Activity

The combination of caffeine and glucose can improve the efficiency of brain activity, according to a recent study in which functional magnetic resonance imaging was used to identify the neural substrate for the combined effects of these two substances

"Our main finding is that the combination of the two substances improves cognitive performance in terms of sustained attention and working memory by increasing the efficiency of the areas of the brain responsible for these two functions," explains Josep M. Serra Grabulosa. This supports the idea of a synergistic effect between two substances, in which each one boosts the effect of the other.
