Neurobiology

In current neuroscience, we know that neurons carry electrical signals across the synapse both to and from the brain to relay information, Throughout history this was not the case. A doctor to the Roman Gladiators, Galen, believed that because the cerebellum was the firm part of the brain, it was responsible for muscle movement. The cerebrum is the softer part of the brain, so he believed perception of different experiences imprinted on this part of the brain. He was generally right in the sense that the brain does control muscle movement, and the cerebrum is mostly responsible for sensory percention. These ideas evolved over the years to the knowledge we have today, that different sections of the brain have different functions and control different parts of our physical and psychological being.
