The urban brain under stress – Associations with residential green space and particulate matter

Description: Urban living is related to an increased risk for the development of stress-related psychiatric diseases. The aim of this study was to examine the influence of environmental variables at the place of residence as potential moderatingor variables for neurofunctional activation during social stress. FMRI data of 42 male subjects, who underwent a social stress paradigm, was coupled with secondary databases providing information about residential amount of green space, air, and noise pollution. With an increasing amount of green-space, stronger activation was found in regions relevant for regulating emotions during the stress compared to the control conditions. In contrast, with increasing particulate matter concentrations we found less activation in the previously mentioned regions as well as in further areas, indicating a general dampening of stress-related activity . This is one of the first neuroimaging studies providing support for the beneficial effect of green space and detrimental effect of particulate matter on neuronal stress processing.
