VKontakte was incorporated on 19 January 2007 as a Russian limited liability company.
Founder Pavel Durov launched VKontakte for beta testing in September 2006, having just graduated from St Petersburg State University.
In February 2007 the site reached a user base of over 100,000 and was recognized as the second largest player in Russia's nascent social network market.
In the same month, the site was subjected to a severe DDo S attack, which briefly put it offline.
The following month, the domain name was registered.
User registration was initially limited to within university circles exclusively by invitation, but the site still grew quickly.
“Individuals who scored high for the resiliency trait on a personality questionnaire tended to be capable of more opioid release during social rejection, especially in the amygdala,” a region of the brain involved in emotional processing, Hsu says.
“This suggests that opioid release in this structure during social rejection may be protective or adaptive.” The more opioid release during social rejection in another brain area called the pregenual cingulate cortex, the less the participants reported being put in a bad mood by the news that they’d been snubbed.
The effect was largest in the brain regions called the ventral striatum, amygdala, midline thalamus, and periaqueductal gray – areas that are also known to be involved in physical pain.Each selected some who they might be most interested in romantically – a setup similar to online dating.But then, when the participants were lying in a brain imaging machine called a PET scanner, they were informed that the individuals they found attractive and interesting were not interested in them.The researchers had actually made sure the participants understood ahead of time that the “dating” profiles were not real, and neither was the “rejection.” But nonetheless, the simulated social rejection was enough to cause both an emotional and opioid response.Suffering slings and arrows differently Hsu notes that the underlying personality of the participants appeared to play a role in how much of a response their opioid systems made.
