Q: Question: Does catechol-O-methyltransferase valine ( 158 ) methionine polymorphism modulate brain networks underlying working memory across adulthood?
Answer: Our findings suggest that the COMTval(158)met polymorphism modulates both the activity and functional connectivity of brain regions within WM networks and most importantly that this effect is exaggerated with increasing age, contributing to the variability in age-related decline in executive cognition.
A:
yes
