[Dave] Which is also analogous to electron flow at the physical level. Larger copper wires enable larger flow not because of their thicken per se but because of their large circumference where the electrons flow. That is also what makes wave guides (hollow tubes) work at higher frequencies. [Krimel] Pretty much. To carry this inexact analogy farther is something like the difference between the electrical grid in your city and the electrical circuits in a computer processor. The electrical grid distributes massive amounts of power throughout a city. Inside a processor much small voltages are used but the awesome complexity of the system is a result of the high resistance or insulating properties of the silicon in which the circuits are embedded. I should also note that in fact the electrical part of neuronal activity is not properly speaking at all like the flow of electron through copper. Rather it s a wave of polarization and depolarization of sodium and potassium ions across the cell membranes of axon fibers of the neurons. Or to break it down for dmb and a few others: it's magic!
