What factor has the most significant effect on brain development during the prenatal period?

Good nutrition is important, because brain growth like the growth of the rest of the fetus' body is influenced by the quality of a pregnant woman's diet. Alcohol and cigarettes be avoided, because these can impair the formation and wiring of brain cells.On the other hand there is some information concerning the effects of environmental factors and their manipulation. During each prenatal stage, environmental factors affect the development of the fetus.

Hope this helps
