Study Establishes Green Tea Boosts Cognitive Function

Published By : 07 Apr 2014 | Published By : QYRESEARCH

Researchers have found evidence through a new study that drinking green tea boosts cognitive functions among humans in general, and working memory in general.

In the new study, researchers working with Professor Christoph Beglinger at the University Hospital of Basel and with Professor Stefan Borgwardt at the Psychiatric University Clinics, report that extract of green tea was found to improve the effective connectivity of the brain. The effective connectivity of the brain refers to the casual influence exerted by the brain over another area.

The effect on connectivity is what also leads to the improvement of the brain’s actual cognitive functions. The subjects that were part of this study tested better for tasks that comprised working memory usage after they had consumed green tea extracts. 

As part of the study, healthy male volunteers were given a drink that comprised green tea extracts following which they were given worked memory tasks to be solved. Scientists studying the task solving skills of these volunteers observed the effect on the brain by making use of magnetic resonance imaging (MRI).

MRI results showed that participants who had consumed green tea extracts showed better connectivity between the frontal cortex and parietal parts of the brain. These findings were found to positively correlate with an improvement in the participants’ task performance. 

Speaking about the findings of the study Borgwardt said that they indicate the role of green tea in increasing the brain’s short-term synaptic plasticity. This study has been published in the latest edition of Psychopharmacology, a scientific journal.
