Prenatal memory
Prenatal memory, also called fetal memory, is important for the development of memory in humans. Many factors can impair fetal memory and its functions, primarily maternal actions. There are multiple techniques available not only to demonstrate the existence of fetal memory but to measure it. Fetal memory is vulnerable to certain diseases so much so that exposure can permanently damage the development of the fetus and even terminate the pregnancy by aborting the fetus. Maternal nutrition and the avoidance of drugs, alcohol and other substances during all nine months of pregnancy (especially the critical period when the nervous system is developing) is important to the development of the fetus and its memory systems. As shown here, certain uses of these substances can entail long-term permanent effects on the fetus that can carry into his or her lifespan. Fetal memory is thus critical to survival of the infant and serves many purposes.
