The brain and spinal cord are among the first organs to develop in a pregnancy, forming within the first few weeks after conception. These structures are vital for the proper growth and development of the embryo.
The cells that are madly dividing in the days after conception will eventually split off to form the placenta, umbilical cord and the baby. By 25 days there is a tiny heart starting to beat, a rudimentary circulatory system and a neural tube that will develop into the CNS, including the brain and spinal cord.
Spina Bifida occurs in this very early stage - the neural tube fails to close completely - leaving the brain and or the spine open to damage.

Which week of pregnancy is the neural tube is formed?
In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the fetus begin to change shape and form the neural tube.
In which trimester of pregnancy does the embryo develop brainwaves and a beating heart?
The heart begins to beat at the end of 3 weeks. Our 'reptilian brain' develops within the first two months, but our conscious thought does not develop until six months into the pregnancy.
