ABSTRACT
The fundamental premise on which the information-processing revolution in psychology was built is that the mind/brain can be profitably understood as a computational device. New techniques for recording from many different neurons simultaneously have created ways to correlate signals from many different brain cells and brain regions in awake-behaving animals. The brain is made up of many different kinds of cells. During brain surgery, Penfield stimulated areas of the frontal lobe and found that this stimulation caused movements in areas of the body. When an ability or behavior is disrupted as a result of a brain lesion, researchers are tempted to conclude that this brain region is responsible for the process that has been affected. One of the most striking observations from split-brain patients is that they are able to name objects presented to their right visual field but not objects presented to their left visual field.
