Q. How much electricity is generated by the brain?

A. Overall the brain is believed to utilize the approximate amount of electricity required to power a 10-watt light bulb, a rather dim bulb, as one researcher put it. The brain’s electrical generating plant, if you will, is housed in the action brain layer or brain stem. There are more connectors between the brain stem and the frontal lobes. Therefore, individuals with an innate preference for using one of the frontal lobes are generally more energetic than those who prefer to use the lower (posterior) lobes.
