| Outline of Final Research Achievements |
In the fetus and infant period, those nutrition depends on the nutritional state of maternal diet. Because brains develop well at these periods, it is affected by the nourishment state of the maternal diet. It is thought that the lipid, which is the component of the cell, affects the development of the brain, but the detailed function in the development of the brain at the fetus and infant period of the lipid nourishment is unclear. In this study, to elucidate a role of the lipid nourishment in the development of the brain of a fetus and infant brain, we performed morphological and behavioral analyses of the pups form the maternal that fed the n-3 polyunsaturated fatty acid deficient diet. As a result, we observed astrocyte decrease in the cerebral neocorex and emotional instability in the n-3 polyunsaturated fatty acid deficient pups.
