Question: how long does it take to devlop a brain

Sonia Lenehan answered on 7 Nov 2018:

Your brain starts developing in the womb around week 3 and continues to develop really quickly up to the moment you are born and after! Some people think this development stops in your 20’s and others think that new cells are still being developed in parts of your brain for the rest of your life! But the size of your head and your brain reach adult size by the time you are 16 or 18 years of age
