"An intimate acquaintance with some of the structural features of the human brain is thus seen to be not only necessary to the physician, but also to the psychologist, the educationalist, and the social worker" - R.J.A. Berry, 1928
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.
