Environmental neuroscience is an emerging field devoted to studying the impact of social and physical environments on brain processes and behaviour. From the various opportunities for social interaction to noise levels and access to green spaces, the characteristics of the urban environment have important implications for neural mechanisms and brain functioning, thus influencing our physical state. The field paints a different image of how cities impact our health and well-being, thus providing a new, scientific layer of understanding that could help architects, urban planners, and decision-makers create more equitable urban environments.
