Take rodents and primates, for instance: In larger rodent brains, the average size of the neuron increases, so the brain inflates very rapidly and gains size much faster than it gains neurons.
Uzmite glodavce i primate, na primjer: U najvećem mozgu glodavca, prosječan broj neurona raste, tako da mozak širi jako brzo i raste puno brže no što dobija neurone.
