| Comments | "Finally, the dendrites (3 times the diameter but 1/9 the length of the axon (Braitenberg and Schüz, 1998)) are polarized on average by 50 mV during an action potential (from simulations of cortical pyramidal cells by A. Roth and M. Häusser, as in Vetter et al., 2001) requiring entry of 3.93×10^7 Na+." |
