Document Summary

Cerebral cortex - the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body"s ultimate control and information-processing center. 20-23 billion nerve cells and 300 trillion synaptic connections. Glial cells - 9x as many cells, cells in the nervous system that support, nourish, and protect neurons; they may also play a role in learning and thinking. (einstein"s brain found a greater concentration of glial cells) Frontal lobes - portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments. Parietal lobes - portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position. Occipital lobes - portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields.
