english: In the past decade or so, mainly due to advances in brain imaging technology such as magnetic resonance imaging, or MRI, neuroscientists have started to look inside the living human brain of all ages, and to track changes in brain structure and brain function, so we use structural MRI if you'd like to take a snapshot, a photograph, at really high resolution of the inside of the living human brain, and we can ask questions like, how much gray matter does the brain contain, and how does that change with age?
non_english: U poslednjoj deceniji, prvenstveno zahvaljujući napretku u tehnologiji snimanja mozga, poput magnetne rezonantne tomografije (MRT), neuronaučnici su počeli da gledaju u živi ljudski mozak svih uzrasta i da prate promene u strukturi mozga i moždanim funkcijama. Tako se za trenutne snimke strukturalne MRT koriste fotografije visoke rezolucije iz unutrašnjosti živog ljudskog mozga. Zato možemo postaviti nova pitanja poput: "Koliko sive mase sadrži mozak? Kako se to menja s godinama?"
