| Research Abstract |
We investigated the serotonergic system and anxiety-related behavior of rats prenatally exposed to ethanol. Anxiety-related behavior tests revealed that the susceptibility to anxiety was decreased in prenatally ethanol-exposed rats. However, their innate fears were facilitated only when they were exposed to intensive aversive stimuli. The abnormalities of anxiety-related behaviors might be attributed to the depressed serotonergic action as a result of a reduced number of serotonergic cells in the midbrain raphe nuclei or the abnormal fluctuation in brain serotonin during development.
