Comments p.289 right column bottom paragraph:"How is such diverse and yet precise localization of Kv channels achieved? This must be a demanding process because neuronal membranes are extremely vast (Fig. 2). It has been estimated that the summed length of dendrites of a hippocampal pyramidal neuron is ~ 20,000 µm which comprises ~ 10^5 µm in area (primary source). This figure could be even greater in cerebeller Purkinje cells of which dendrites contain hundreds of branches. The axon can also be very long and extensively arborized."
