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: V preteklem desetletju, predvsem zaradi napredka tehnologij slikanja možganov, kot je slikanje  z magnetno resonanco ali MR, so nevroznanstveniki začeli raziskovati delovanje možganov živih ljudi vseh starosti in slediti spremembam v strukturi in delovanju možganov. Uporabljamo strukturne MR, da naredimo posnetek, fotografijo, res visoke ločljivosti, notranjosti možganov živega človeka,  in si zastavimo vprašanja kot, koliko sivine imajo možgani in kako se spreminja s starostjo?
