Brain Regions Important in Behavioral Effects of Prenatal Alcohol Exposure

While there has been considerable progress in identifying areas of the brain damaged by fetal alcohol exposure that are associated with neuropsychological brain-emotionsdysfunction, there is less data available to demonstrate similar associations with behavioral abnormalities. However, it is possible to match behavioral problems typical of FASD children with brain areas that control those behaviors. For example, attention is regulated by several brain areas, including the parietal cortex (purple area at right). Judgment is also a behavior that is regulated by a part of the cerebral cortex in the front of the brain called the Orbitofrontal Cortex (in orange). In fact, the poor judgment exhibited by someone drinking a few too many drinks is due to alcohol’s effects in the orbitofrontal cortex. The orbitofrontal cortex is important in impulsiveness as well. The cerebral cortex communicates with structures beneath it, such as the Amygdala (in blue), which is very important in mood, anxiety, and emotions. The caudate nucleus, mentioned above, helps provide the motivation to carry out activities that involve movement.
