Comments p.762 right column 2nd paragraph:"The percentage of energy used on synapses may be even larger in the primate cortex, where the number of synapses per neuron is larger (Abeles, 1991). In contrast, the energy use of the white matter is 3-fold lower than the gray matter, mainly because it has an 80-fold lower density of synapses (primary source)."
