Stress in the City: Brain Activity and Biology behind Mood Disorders of Urbanites relates to The Sensation and Perception section in chapter four of our text book. Sensation and Perception play two complimentary, but different roles in how we interpret the world. Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell. This information is sent to our brains in raw form where perception comes into play. Perception is the way we interpret these sensations and therefore make sense of everything around us. The environment in which we are in can have a large effect on our daily lives. Our environment can even effect how our brain responds to different stimuli.
Being born and raised in a major urban area is associated with greater lifetime risk for anxiety and mood disorders. Until now, the biology for these associations had not been described. A new international study, which involved Douglas Mental Health University Institute researcher Jens Pruessner, is the first to show that two distinct brain regions that regulate emotion and stress are affected by city living. The study is published in the journal Nature. It may help explain why mood disorders like depression and mental illnesses like schizophrenia are more common in city dwellers than in those living in less densely populated areas.
