Abstract in brief

Human brain development, specifically the growth of the corpus callosum, continues into the mid-20s, indicating that structural brain changes extend beyond adolescence.
The study measured the corpus callosum's size through MRI scans over two years in 90 subjects of various ages, finding it increases until the early twenties.
These findings, combined with other research, suggest the corpus callosum is part of the brain's most advanced and last-to-mature neural networks, supporting ongoing cognitive development into adulthood.]

@iamabdullaahsan @m07player @ibzynn Body-wise, physical maturity arrives at around 14-16 yrs. Mentally wise, brain growth stops at around 25, meaning they attain full 'mental' maturity in their 20s. Thus, the age of adulthood is put at 18 https://t.co/cB99FWmtuL

If studies like this are correct, there is a good argument that the age of consent needs increasing. https://t.co/14NUDnSJB2

@Mythras2150 @tiekuoqut @AFatMasoCat @AntiCaughtIn4K In a matter of speaking. The actual growth of the brain stops in the mid 20's though. https://t.co/1ainYUS5D2

@shippers_i @Alliury @Voyboy I hope you didn't get that number from the Promised Neverland. There is a scientific consensus that in most individuals the brain does not stop developing until adulthood. https://t.co/8if105LT2d https://t.co/8bcAaxph12. and many more studies on pubmed
