The Human Brain is one of the most complicated objects in the universe. Although it weighs less than 3 pounds, it manages everything from our heart rates to our thoughts and feelings. This is the major control network for the body's functions and abilities: conscious communication with our body and automatic operation of vital organs. The functions of the brain are varied, and include: thinking, perception (sensing), emotion, signaling, and many of our physical functions. Our cognition, feelings and behavior are all the result of our brains.
