For a long time, it was believed that the prefrontal cortex\u2014the part of our brain responsible for decision-making and impulse control\u2014didn\u2019t fully develop until the age of 25, which is when we\u2019d become proper adults, basically. But this isn\u2019t actually true; it was an oft-repeated myth that probably stemmed from an old study in which scientists looked at brain scans up until<\/em> the age of 25. But no matter. We heard \u201c25\u201d and we ran with it. Probably because it sounded good. We were all dumb at 23, right?<\/p>\n

That said, if you\u2019re interested in when the brain truly does<\/em> reach a certain level of maturity, a new study (not just an overzealous TikToker) may have quite a solid answer. According to researchers at the University of Cambridge, who scanned the brains of around 4,000 people between the ages of zero and 90, the brain stays in its adolescent phase up until\u2026 our early 30s, which is when we \u201cpeak.\u201d That\u2019s right: we\u2019re not adults until we\u2019re approximately 32. Good news for those who don\u2019t have everything figured out at 28, then. You have time!<\/p>\n

In the study, which was published by Nature Communications<\/em>, the brain evolves in five broad phases throughout our lives, split up by four pivotal \u201cturning points.\u201d The \u201cchildhood brain\u201d runs from birth until a turning point at the age of nine, when it transitions to the \u201cadolescent\u201d phase\u2014an era that lasts right up until the age of 32, on average.<\/p>\n

\u201cOur early thirties see the brain\u2019s neural wiring shift into adult mode,\u201d writes Fred Lewsey at the University of Cambridge. \u201cThis is the longest era, which lasts over three decades. A third turning point around age 66 marks the start of an \u2018early ageing\u2019 phase of brain architecture. Finally, the \u2018late ageing\u2019 brain takes shape at around 83 years old.\u201d<\/p>\n

This study is quite a big deal, it turns out. \u201cThis study is the first to identify major phases of brain wiring across a human lifespan,\u201d says Dr. Alexa Mousley, a Gates Cambridge Scholar who led the research, adding that, \u201cThese eras provide important context for what our brains might be best at, or more vulnerable to, at different stages of our lives.\u201d<\/p>\n

Don\u2019t get too excited, though\u2014it\u2019s not like you suddenly become much smarter or more logical at the magical age of 32, which is what one might hope if you are\u2014cough<\/em> \u2013 hovering around that age, like some of us. It would be more accurate to say that the brain\u2019s architecture stabilizes around this time, and it doesn\u2019t hugely change again for another 30 years. This corresponds with a \u201cplateau in intelligence and personality\u201d based on other studies, say researchers. So, maybe it\u2019s not so good after all?<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Basically, you get more stuck in your ways\u2014which at least partly explains why you can\u2019t convince your boomer parents of anything once they\u2019ve made their minds up. That\u2019s science, baby.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n
