| Outline of Final Research Achievements |
Evidences from both of neurobiological and epidemiological studies raise the possibility that malnutrition in early life could lead to the later development of physical as well as psychiatric disorders. In the present study, we examined the effect of food deprivation during pregnancy, to simulate maternal malnutrition, on later neurodevelopment and behavioral disturbance in the rat. The results suggest that exposure to maternal nutrient-restriction in utero is associated with decreased neurogenesis in the hippocampus in the adult rat. Furthermore, behavioral studies revealed that food deprivation during pregnancy had significant effects on maternal behaviors. These results are suggestive of possible involvement of malnutrition in early life in the pathophysiology of psychiatric disorders.
