This is a result of a research published in the Human Psychopharmacology, Clinic and Experimental journal, which was led by Josep M. Serra Grabulosa, from the Department of Psychiatry and Clinical Psycobiology at the University of Barcelona.
“Our findings showed that the combination of these two substances enhance cognitive performance. The main focus of work-related brain and memory continuously,” he said. These findings indicate a synergistic effect between these two substances, in which each enhances the effect of one another.
For this study, a team of researchers from the University of Barcelona used MRI (magnetic resonance imaging) to analyze the brain activity during the study to evaluate the ability of the brain basis in improving cognitive tasks of everyday life, which is continuous focus and memory. Participants were tested after drinking beverages that contain either glucose, caffeine or the two combined, or placebo consisting only of water. Tests carried out with samples from 40 healthy volunteers at the Center for Diagnostic Imaging Hospital Clinic Barcelona.
In particular, the research team found that people who consumed a combination of caffeine and glucose showed reduced brain activation in bilateral parietal cortex and left prefrontal cortex – two areas that actively participate in the process of focusing and working memory. “The activities decreased but there was no decline in the performance which means the brain is more efficient under the combined influence of the two substances,” he said.
Participants who had combination of two substances, require less resources to produce the same level of performance required by participants who had placebo or only caffeine or glucose solely.
The team had previously investigated the effects of caffeine and glucose consumption showed improvement in declarative memory and attention span without significant change from where the participant came from. Conclusions suggest that the combination of glucose and caffeine has beneficial effects on task-related brain focus and memory.Tagged with: brain activation, brain activity, cognitive performance, cognitive tasks, continuous focus, human psychopharmacology, magnetic resonance imaging, parietal cortex, sweet coffee, synergistic effect, working memory,
