![]() ![]() They couldn’t distinguish the impacts of solely experiencing the act of drinking coffee from the effects of the experience combined with caffeine intake.Īdditionally, they didn’t test the theory that coffee drinkers might be experiencing relief from withdrawal symptoms. However, the researchers acknowledged some limitations in their study. Limitations of the study open future new exploration paths Or the psychological expectations tied to the drink could play a role. Factors like coffee’s distinctive aroma and taste possibly drive this finding. She also suggested that while some of the effects are likely related to caffeine, other effects seem unique to coffee. “Acute coffee consumption decreased the functional connectivity between brain regions of the default mode network…the subjects were more ready for action and alert to external stimuli after having coffee.” Maria Picó-Pérez of Jaume I University, the first author of the study, breaks down the findings. Caffeine and a cup of coffee have different brain impactsĭr. You will need that full coffee experience. In short, if you want to feel not only alert but also ready for action, merely ingesting caffeine won’t cut it. Remarkably, when participants consumed only caffeine, the researchers did not observe this heightened connectivity. These brain regions are responsible for working memory, cognitive control, and goal-directed behavior. However, what really sets coffee apart is its ability to increase connectivity in the higher visual network and the right executive control network. Their study demonstrated that both caffeine and coffee can gear individuals up to transition from a state of rest to a state of task-oriented work. ![]() This suggests that whether it’s caffeine or a cup of coffee, either will do the trick. Indeed, their results showed that both drinking coffee and consuming caffeine reduced the connectivity of the default mode network. Results from the morning cup of coffee vs. This region is involved in self-reflection and introspection. The other brain region they focused on was the default mode network. This brain region is linked with executive memory. One of the networks they scanned is tied to the prefrontal cortex. They anticipated that the MRI scans from the coffee drinkers would reveal enhanced integration of certain brain regions. The researchers’ hypothesis was based on the known neurochemical impacts of coffee. During the MRI scans, the researchers asked the participants to relax and let their thoughts wander. One scan done before, and the other scan done thirty minutes after consuming caffeine, or a standardized cup of coffee. They then conducted two quick functional MRI scans following the interviews. The researchers gathered sociodemographic data through interviews. The researchers instructed these participants to abstain from any food or caffeinated drinks for a minimum of three hours prior to the study. The experiment involved volunteers who consume at least one cup of coffee daily. How they conducted the morning cup of coffee/placebo study They did so by gaining a deeper understanding of the mechanisms that trigger these effects. The researchers hoped to uncover the potential benefits and factors that can influence this phenomenon. He explains that it’s a general belief that “coffee increases alertness and psychomotor functioning.” Nuno Sousa from the University of Minho is the leading author of this study. They focused on regular coffee-drinkers to find out what was actually giving them the energy boost. ![]() To find the answers, a group of Portuguese researchers have embarked on a scientific journey. ![]()
