|Frontal Lobe||Deals with the most integrated brain functions: thinking, conceptualizing and planning. It also plays a major part in the conscious appreciation of emotion.|
|Parietal Lobe||Functions connected with movement, orientation, calculation and certain types of recognition.|
|Temporal Lobe||Deals with sound, speech comprehension (usually the left brain only) and some aspects of memory.|
|Occipital Lobe||Made up entirely of visual processing areas.|
The frontal motor cortex primarily controls the movement of the hands and face.
A thick band of axon fibers, 80 million or so, which connect the brain cells in left hemisphere to those in the right hemisphere. The two sides keep up a continuous intimate conversation via this neural bridge that produces a seamless perception of the world, and a single stream of consciousness. There is a difference in size between men and women -- women's are relatively larger.
