Abnormal Brain Development in FAS

During prenatal development, different organ systems form and mature at different times. An individual is exposed to a harmful environmental agent known to cause major structural defects in the central nervous system (like the brain and spinal cord). Based on the principle that vulnerability is highest when a system is first forming, which period of exposure would most likely result in the most severe structural damage to the central nervous system?
