Prenatal brain development. prenatal brain development begins in the third gestational week with the differentiation of stem cells, which are capable of producing all the different cells that make up the brain (stiles & jernigan, 2010). the location of these stem cells in the embryo is referred to as the neural plate. From 9–12 weeks, the sex organs begin to differentiate. at about 16 weeks, the fetus is approximately 4.5 inches long. fingers and toes are fully developed, and fingerprints are visible. by the time the fetus reaches the sixth month of development (24 weeks), it weighs up to 1.4 pounds.
