Description

DESCRIPTION (provided by applicant): The effects of ethanol on a fetus are extensive, devastating, and often permanent. Depending upon the population, ethanol affects as many as 2-5% of all live births. The most profound effects of ethanol are on the nervous system. Gestational ethanol exposure causes behavioral changes such as hyperactivity, attention deficit hyperactivity disorder (ADHD), learning and memory deficits, alterations in social behavior, and mental retardation. Such behavioral changes can also be seen in animals exposed to ethanol in the prenatal period, thus they provide good models for examining the underpinnings of the changes. One system that is particularly important for both social behavior and ADHD is the somatosensory system. Blocking sensory information within this system is sufficient to negatively affect social behavior. Ethanol causes alterations in the structure and function of this area. We will test the hypothesis that exposure to ethanol during development that causes structural alterations in somatosensory cortex will negatively affect behavior (including social behavior) and alter the neurochemistry of this region. Further, we will test the hypothesis that supplementation with docosahexaenoic acid, an omega-3 fatty acid, in the postnatal period will reverse ethanol-induced deficits in behavior, neurochemistry, and brain structure.
