english: When they get active, they need increased blood flow to supply that activity, and lucky for us, blood flow control to the brain is local, so if a bunch of neurons, say, right there get active and start firing, then blood flow increases just right there.
non_english: Kada su aktivni, potreban im je povećani protok krvi za snabdevanje te aktivnosti i na našu sreću, kontrola protoka krvi u mozgu je lokalna, pa ako se gomila neurona, recimo tamo počne aktivirati i paliti, baš tamo se i protok krvi povećava.
