english: The arrows indicate peak gray matter volume in prefrontal cortex. You can see that that peak happens a couple of years later in boys relative to girls, and that's probably because boys go through puberty a couple of years later than girls on average, and then during adolescence, there's a significant decline in gray matter volume in prefrontal cortex.
non_english: Strelice označavaju vrhunac zapremine sive mase u prefrontalnom korteksu. Možete videti da se taj vrhunac kod dečaka dostiže nekoliko godina kasnije nego kod devojčica, verovatno zbog toga što dečaci u proseku prolaze kroz pubertet nekoliko godina kasnije nego devojčice, a zatim tokom adolescencije dolazi do značajnog smanjenja u zapremini sive mase u prefrontalnom korteksu.
