Comments "The percentages of the expenditure maintaining resting potentials, propagating action potentials through a neuron, and driving presynaptic Ca2+ entry, glutamate recycling, and postsynaptic ion fluxes, are shown (100% = 3.29×10^9 ATP/neuron/s)." For distribution [in rat neocortex] updated to account for mammalian action potentials using less energy than those in squid giant axon see Harris et al. 2012 p.764 figure 2A link
