Unformatted text preview: recall the copper wire analogy. leak will positive charge leak out of the axon before it moves from point A to B, B to C, etc.? capacitance e.g., the amount of charge needed to depolarize segment B to spike threshold. if the capacitance is low then only a small amount of charge is needed to depolarize segment B, and residual charge can spread to (& depolarize) segment C. .. conduction will be fast if the capacitance is high then a large amount of charge is needed to depolarize segment B, and this leaves little or no residual charge to depolarize segment C conduction will be slow...
