Why the fuck do unmyelinated axons with larger diameters conduct action potentials faster?
I can't wrap my head around it. Sure, if you have a larger diameter, then that means more overall membrane, which means more ion channels, allowing a larger amount of ions to cross the membrane at any one time, increasing the current, which makes the membrane reach the threshold potential faster.
BUT CONDUCTANCE IS FUCKING LATERAL, isn't it? I mean, its along the membrane. An axon depolarises depending on the activity of the ion channels directly adjacent to it. So wouldn't it be a case of ion channel density that increases conduction velocity?
Not homework, not asking /sci/ to do shit for me, just reading up on this shit and can't seem to understand this little part right here.

>"Complexity theory's great contribution is showing that the Second Law of Thermodynamics is only part of the story, since some systems tend toward order, not disorder. Within nature, then, there is a deep order. But this order is not caused by the hand of God, complexity theorists are quick to point out. For physicists this is quite natural but for biologists self-organization still appears mystical, a return to pre-Darwinian theories."
What does /sci/ think?
