However, drinking coffee also increased the connectivity in the higher visual network and the right executive control network – parts of the brain that are involved in working memory, cognitive control, and goal-directed behavior. They found that the connectivity of the default mode network was decreased both after drinking coffee and after taking caffeine, which indicates that consuming either caffeine or coffee made people more prepared to move from resting to working on tasks. During the functional MRI scans, the participants were asked to relax and let their minds wander.īecause of the known neurochemical effects of drinking coffee, the scientists expected that the functional MRI scans would show that the people who drank coffee had higher integration of networks that are linked to the prefrontal cortex, associated with executive memory, and the default mode network, involved in introspection and self-reflection processes. They interviewed the participants to collect sociodemographic data, and then did two brief functional MRI scans: one before and one 30 minutes after either taking caffeine or drinking a standardized cup of coffee. The scientists recruited people who drank a minimum of one cup of coffee per day and asked them to refrain from eating or drinking caffeinated beverages for at least three hours before the study. “When you get to understand better the mechanisms underlying a biological phenomenon, you open pathways for exploring the factors that may modulate it and even the potential benefits of that mechanism.” A caffeine kickstart “There is a common expectation that coffee increases alertness and psychomotor functioning,” said Prof Nuno Sousa of the University of Minho, corresponding author of the study in Frontiers in Behavioral Neuroscience and Field Chief Editor of the journal. Portuguese scientists studied coffee drinkers to understand whether that wakefulness effect is dependent on the properties of caffeine, or whether it’s about the experience of drinking coffee. Coffee is often thought to make you feel more alert, so people drink it to wake themselves up and improve their efficiency. Scientists testing coffee against plain caffeine found that plain caffeine only partially reproduces the effects of drinking a cup of coffee, activating areas of the brain that make you feel more alert but not the areas of the brain that affect working memory and goal-directed behavior.įor many people, the day doesn’t start until their coffee mug is empty. Scientists find that the boost you get from a morning coffee can’t be replicated with plain caffeine. This suggests that the unique benefits of coffee may extend beyond its caffeine content, potentially linked to the experience of drinking it or withdrawal symptom relief. Give us a follow there: you like our caffeine mug, then you might also like our caffeine molecule necklace.A study by Portuguese scientists reveals that drinking coffee activates brain areas related to alertness, working memory, and goal-directed behavior, more than plain caffeine.

Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks, enjoy great popularity in North America, 90% of adults consume caffeine daily. Caffeine is the world’s most widely consumed psychoactive substance, but, unlike many other psychoactive substances, is legal and unregulated in nearly all jurisdictions. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness.
