Brain electric pulses

  1. Oct 3, 2007 #1
    The senses in our body sends electric pulses to the brain. Once it reaches the brain, what happens to the pulse (in the context of conservation of energy)?

    The brain uses approximately 100 watts of power. Remember that half of the body's heat loss (the result of dissipated energy) is radiated from the head.

    I don't believe there are any definitive studies on that. There are just a ton of chemicals you would have to account for. Although it makes a decent anaolgy, you shouldn't think of those pulses in the same way you think of a current in a wire.
