Facebook and Your Brain

Does the use of Facebook affect your brain size? The answer is...sort of. According to a study conducted by the University College in London, people who are more social on social tend to have larger amygdalae (a mass of gray matter deep within each cerebral hemisphere). People who are more social online have an increased size in parts of their brains which control emotions, the ability to read social cues, and memory. Researchers are still not certain if social network sites are responsible for these observations, and if there is a third variable contributing to these findings. Bottom line, there's a correlation between one's brain and the number of friends he or she has. These changes can be attributed to more social cues, etc. that are exchanged when people interact often, which might not hold true for people are not social.
