Brief summary

The paper analyzes the results of functional magnetic resonance imaging in the group of people with opioid addiction, in consumers of androgenic anabolic steroids and compared with the indicators of the group of somatically healthy people who are fond of social networks. Brain activation zones in the areas of "memory", "cognitive control", "motivations and emotions" and "visual integration" were determined in the groups of opioid and androgenic anabolic steroid users. In people who are fond of social networks, the zones of the limbic system in most cases were not active, but the activation in the hypothalamus and the orbitofrontal cortex do not exclude the possible influence of social networks on the formation of Internet addiction.


Key words

functional magnetic resonance imaging, addiction, androgenic anabolic steroids, Internet addiction
