Does a fetus have a brain at 7 weeks?

Week 7: Baby's head develops
Seven weeks into your pregnancy, or five weeks after conception, your baby's brain and face are growing. Depressions that will give rise to nostrils become visible, and the beginnings of the retinas form.

Lower limb buds that will become legs appear and the arm buds that sprouted last week now take on the shape of paddles.


Your fetus will begin the process of developing a brain around week 5, but it isn’t until week 6 or 7 when the neural tube closes and the brain separates into three parts, that the real fun begins.
