The developing nervous system is most vulnerable to teratogens during the embryonic period, which occurs from approximately week 2 to week 8 of pregnancy. This is when the neural tube is forming and the basic structures of the nervous system are being established. Teratogens, such as alcohol or certain medications, can interfere with this development and cause permanent damage. Therefore, the period of 1 to 2 weeks after conception, which marks the beginning of the embryonic period, is the most critical time for the developing nervous system.
