There’s this idea that something happens in the human brain when we turn 25. Suddenly, we can rent a car without fees. Make rational decisions. We may even regret some of our past… indiscretions. All because we’re developed…right? Well, a recent paper in <a href="https://www.nature.com/articles/s41467-025-65974-8"target="_blank" >the journal Nature</a> suggests that may not be the case. Neuroscientists found four distinct turning points in brain development across the human lifespan – and that the brain may be in its “adolescent” phase until about the age of 32.  Interested in more of the science inside your brain?
