Neural correlates of individual differences in affective benefit of real-life urban green space exposure

Abstract

Psychiatric morbidity is high in cities, so identifying potential modifiable urban protective factors is important. We show that exposure to urban green space improves well-being in naturally behaving male and female city dwellers, particularly in districts with higher psychiatric incidence and fewer green resources. Higher green-related affective benefit was related to lower prefrontal activity during negative-emotion processing, which suggests that urban green space exposure may compensate for reduced neural regulatory capacity.
