The neural plate forms in the third week, the anterior portion of which gives rise to neuroectoderm, tissues fated to form the tissues of the central nervous system (CNS).

Alcohol-induced brain damage can occur at any time during pregnancy (and during breast-feeding as well!). During all 3 trimesters (and beyond), the major cells of the brain, the neurons and glia, are formed from stem cells (neurogenesis and gliogenesis, respectively). Then, neurons multiply, grow and establish their branches and connections. The long axons of neurons become surrounded by myelin, which insulates and protects the neurons and allows electrical information to be transmitted along the axon. When a pregnant mother drinks alcohol during periods of neurogenesis, the alcohol actually kills the neural stem cells, reducing neurogenesis.
