3、ough to the time of the study. Brain structure was studied using 3D magnetic resonance imaging (MRI). Working memory and inattentiveness(注意力不集中)were graded with computers.“This is the first study that shows the association between long-term exposure to green space and brain structure.” Says Dr. Paya
4、m Dadvand, the leading researcher of the study, “Our findings suggest that exposure to green space early in life could result in beneficial structural changes in the brain.”The findings show that long-term exposure to greenness is positively associated with white and grey matter volumes in several p
