UNITED KINGDOM–(ENEWSPF)–2 February 2012. Researchers are suggesting that there is a link between the number of friends you have and the size of the region of the brain â known as the orbital prefrontal cortex â that is found just above the eyes. A new study shows that this brain region is bigger in people who have a larger number of friendships. Their study is published on 1 February 2012 in the journal, Proceedings of the Royal Society B.
