The velocity of spike propagation is proportional to the following combination of factors: 1 a C V RR, m m Where a is the radius of the axon, R, and R; are specific resistances of the membrane and the internal buffer, respectively. If we double the radius and simultaneously increase the concentration of salt inside the axon twice (i.e. R; decreases two times), by how many fold will the velocity change?
