Green Tea enhances working memory and brain connectivity

8 Jul

The sample size is very small, so these results must be treated with some caution.

Science Abstracts

The results seem to indicate green tea appears to improve working memory and fMRI showed increased connectivity between parietal and the frontal cortex. It’s a small test group, hopefully these results will be reflected in a larger study.

Green tea extract enhances parieto-frontal connectivity during working memory processing

Rationale
It has been proposed that green tea extract may have a beneficial impact on cognitive functioning, suggesting promising clinical implications. However, the neural mechanisms underlying this putative cognitive enhancing effect of green tea extract still remain unknown.
Objectives
This study investigates whether the intake of green tea extract modulates effective brain connectivity during working memory processing and whether connectivity parameters are related to task performance.
Material and methods
Using a double-blind, counterbalanced, within-subject design, 12 healthy volunteers received a milk whey-based soft drink containing 27.5 g of green tea extract or a milk whey-based soft drink without green tea as…
