Brain Electric Pulses: What Happens to the Pulse?

[jobyts]

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)?

 

[Loren Booda]

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.
