english: So the reason why the human brain costs so much energy is simply because it has a huge number of neurons, and because we are primates with many more neurons for a given body size than any other animal, the relative cost of our brain is large, but just because we're primates, not because we're special.
non_english: Tako da je razlog zbog kojeg ljudski mozak troši toliko energije, jednostavan, jer ima veliki broj neurona, i zato što smo mi primati sa mngo većim brojem neurona u odnosu na veličinu tela od bilo koje druge vrste, relativna potrošnja našeg mozga je ogromna ali samo zato jer smo mi primati, ne zato što smo posebni.
