The brain consumes electrical energy at the rate of 25 watts and occupiesvolume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items ofinformation. Every brain cell is directly connected to many other cells. As a result, the cells inwhich information is stored can communicate with thousands of other cells.Incontrast,jhe^computer^consu;mes_1000,000wwattsofelectricaLpower^andoccupieshundredsofcubicJ:eeLofspace.^rhe^computermemoryjisJlike^acellofpigeonholes^withnojhinking^capacityandnoconnectionselsewhere.
