The brain has four different lobes that function and perform differently from the other. The Adult human brain weighs about 3 lbs. containing about 85% water that consists of gelatin and over 100 billion neurons (Bostwick & Weber, 2013). The brain is responsible for controlling the bodies many functions and interactions with the outside world.
