How your baby’s brain develop before birth

You might not even know you are pregnant, when you baby’s brain is already growing at an astonishing rate.  The brain and neural cord begin as a simple neural tube. During week four, the brain separates into three sections; the forebrain, mid-brain and hind-brain. By week six it further divides into the left and right hemispheres. At this stage scientists claim to pick up some brain wave activity already (O”Rahily & Mueller 2008). From the sixth month of pregnancy the outer layer of the brain, the cerebral cortex, starts to develop convolutions (like the deep grooves of a walnut without its shell). More and deeper “folds” are associated with higher intelligence in humans, but this theory is yet to be proved conclusively. At the peak of development, an embryo’s brain grows by 250 000 neurons a minute (Nowakowski 2006). At birth it is estimated that a new-born’s brain has an amazing 100 billion neurons. This is where WePlaySmart comes in; we are passionate about your baby’s amazing potential and want to empower you to make the most of it by giving your baby a kick-start!
