Coffee can help you awake, but what caffeine actually does with your brain as soon as you sleep? Using the II, the researchers team has the answer: it affects the “critical” brain.
In a study published in April at Nature Communications Biology, a team of researchers from Universite De Montreal spilled new light on how caffeine can change sleep and affect brain recovery – both physical and cognitive in one night.

The study was headed by Philip Tolke, the UDEM (Coco Lab) cognitive and computing laboratory, and is headed by Karim Jerby, a psychology professor and a Mila, Quebec.
Conclusions of the study:
Working with the psychology of sleep and age Professor Julie Karir and her team at the center of advanced sleep research, scientists used II and electroencephalography (EEG) to study the effects of caffeine on sleep.
They first showed that caffeine increases the complexity of brain signals and increases the “critical” brain during sleep. Interestingly, this was more pronounced in young adults.
“Criticism describes the state of the brain that is balanced between the order and the chaos,” Erbi said.
“It’s like an orchestra: too quiet and nothing happens, too chaotic and cacophony. Critical is a happy environment where brain activity is organized and flexible. In this state, the brain is optimally functioning: it can effectively process information, quickly adapt, study and make decisions,” Erbi added.
Added carrier: “Caffeine stimulates the brain and pushes it into a state of criticism, where it is more unwavering, wary and jet, while it is useful during the day for concentration, this condition may interfere with rest at night: the brain is not relaxed or properly healed.”
Researchers also found amazing changes in the electrical rhythms of the brain during sleep: caffeine weakened more slow fluctuations, such as theta and alpha – usually associated with deep, restorative sleep – and stimulated beta, which is more common during wakefulness and mental activity.

“These changes suggest that even during sleep, the brain remains in a more activated and less restorative condition under the influence of caffeine,” says Erby, who also has a Canadian department in computing neurology and cognitive neurovisualizing. “This change in the rhythmic activity of the brain can help explain why caffeine affects the effectiveness with which the brain recovers at night, with potential consequences for memory processing.”
The study also found that the effect of caffeine on the brain dynamics was much more pronounced in young people between the ages of 20 and 27 compared to middle -aged participants between the ages of 41 and 58 years, especially during sleep, a dream -related phase.
