| Research Abstract |
Previous study revealed that abnormalities of brain development induced by fetal alcohol exposure(FAE) were recovered by administration of serotonin 1A receptor agonist during period of brain development. In addition, we found disruption of dynamics state of serotonin under fearful state in mature FAE animals. These results suggest that FAE induces abnormalities of central nerves system via reduction of serotonergic function, mainly meditated by serotonin 1A receptor during period of brain development and prolonged abnormality of 5-HTergic function lead to anxiety-like behavior in mature FAE animals.
