batteries???

Submitted by jchung01@brynma... on Sat, 02/23/2008 - 10:39pm.

The fact that the human body is a battery is still a confusing topic for me.  I understand the point that there is a voltage gradient that triggers certain movements and inputs/outputs like a battery, but I think to isolate the brain like a battery is too much of a forced analogy. 

It makes sense that the voltage gradients trigger a current of action potentials throughout a chain of neurons, however, wouldn't this make more sense as the brain being more of an electric circuit than a battery?  The actual energy source isn't from the brain itself, it is from our digestive system....

I hope I am not missing a huge point here...
