||"To calculate the energy needs of various components
of signaling in the brain, [researchers] analyze the transmitter release triggered by a single action potential passing
through a typical neuron."
||"Summing these estimates for presynaptic Ca2+ entry,
vesicle cycling, postsynaptic actions, and glutamate recycling,
the energy expended per vesicle of glutamate
released is 1.64×10^5 ATP molecules."
