Phone calls, emails and social networking all contribute to the physical landscape of your brain. Researchers from the University of Oxford found that people with wider social networks have increased brain connectivity between regions and wider anterior cingulate and dorsolateral prefrontal cortexes.
The findings, presented at the annual meeting of the Society for Neuroscience, showed 18 brain scans of participants with varying sizes of social networks.
While an association was found between specific brain regions, brain connectivity and the size of social networks, research did not find if having a big social network has any further impact on your brain.
