Researchers at the University College London have found a connection between the number of Facebook friends a person has and the amount of “grey matter” in the amygdala, the sulcus, the left middle temporal gyrus, the right entorhinal cortex, and the superior temporal sulcus. “Grey matter” in the brain is the layer where mental processing takes place. While the study uses Facebook as an example, the results point to the impacts the Internet and social networking may be having on our brains.

"For centuries, people have known that exercise remodels muscles, rendering them more durable and fatigue-resistant. In part, that process involves an increase in the number of muscle mitochondria, the tiny organelles that float around a cell’s nucleus and act as biological powerhouses, helping to create the energy that fuels almost all cellular activity. The greater the mitochondrial density in a cell, the greater its vitality. Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for obesity, diabetes and heart disease in people. It is a very potent cellular reaction."

Scientists have discovered that the amygdala, a small almond shaped structure deep within the temporal lobe, is important to a rich and varied social life among humans. The finding was published this week in a new study in Nature Neuroscience and is similar to previous findings in other primate species, which compared the size and complexity of social groups across those species.
