Question: How do brains grow

Sonia Lenehan answered on 8 Nov 2018:

Brains start growing the moment you are in the womb! And the continue to grow until you are 16/18 years of age. When you are born your brain weighs about 400g, by the time it is fully grown it weighs 1400g. Your brain grows using energy from your food and it grows along the same rates at the rest of your body so dont end up with a very big body and a tiny head!!
