New research has investigated caffeine’s effect on neurons at dose levels comparable with normal consumption habits. The researchers stimulated neurons with normal consumption levels of caffeine over periods of 1, 3 and 9 hours. The experiment revealed that caffeine upregulated some neuronal processes, and downregulated others. Overall, the study results show that caffeine promotes neuronal connections, providing possible mechanistic insights into caffeine’s enhancing effects on memory and cognition.
