As Social Network Grows, so Does the Brain
Monkey brains grow bigger with every cagemate they acquire, according to a new study showing that certain parts of the brain associated with processing social information expand in response to more complex social information.
“Interestingly, there are a couple of studies in humans by different research groups that show some correlation between brain size and the size of the social network, and we found some similarities in our studies,” study researcher Jerome Sallet, of Oxford University in the U.K., told LiveScience.
“[Our study] reinforces the idea that the human social network was built on something that was already there in the rhesus macaques.”
