How many friends can the brain maintain? Social groups are important not only in the human world, but in the animal kingdom as well. Many creatures are known to travel in packs. BrainCraft tries to discover how many friends can actually be held in the social brain.

Vanessa Hill of PBS Studios talks about different scientific hypotheses and theories on how the human brain has evolved and what that means for social interaction. In comparison to other primates, humans hold the largest neocortex, which ultimately means that, hypothetically, we're able to maintain the largest amount of consistent social relationships.
