It was concluded that the cities can help stimulate the brain cells of citizens and maintain their brain activity at a certain level of productivity.
This article considers the concept of a city as an organized and complex system, the main inhabitant/consumer of which is a human being. The human being, in its turn, is also a complex organized system. Separately, the functioning of both these systems is well enough studied, however to date in science little attention has been paid to the interaction of these systems with each other. The main object of study in the article is the psychological state of a person in an urban environment. The concepts of interest, excitement, boredom, stress, and so forth are investigated and their impact on physical health. Moreover, the problem of interaction of the real world with virtual technologies-their confrontation and mutual help in an urban context is also considered. At the end, there are several assumptions about the return of full-bloodedness to the streets of modern cities. It was concluded that the cities can help stimulate the brain cells of citizens and maintain their brain activity at a certain level of productivity.
