“The human brain… is one of the most complicated material objects in the known universe. The number of possible active pathways of such a structure far exceeds the number of elementary particles in the known universe” - G.M. Edleman (Nobel Prize, 1972)
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.
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.
