Still more.: Some of the connection between the areas of the brain in the so-called "white matter regions" continue to develop as late as age 25 or 30.

More: The cited estimate differs with gender.The average female brain finishes its interconnections by age 22 while the male is delayed until 25. There is some overlap in populations but this is the basics. These interconnections do not define "responsibility" or good judgement. They are a simple maturational or biologic event.
