Outline of Final Research Achievements

To determine which aspect of neurogenesis regulation is influenced in the hippocampus of pups obtained from dams in the bite-raised condition during pregnancy, we examined the proliferation of newborn cells in the pup hippocampus and spatial learning ability.
Plasma corticosterone levels of bite-raised group in dam were greater than those of the control group. The dams of maternal bite-raised condition was decreased the proliferation of newborn cells in the pup hippocampus and spatial learning ability. Exposure to an enriched environment enhances, hippocampal cell proliferation and spatial learning ability were improved.
